I have an app that before worked fine but recently won't run.
Before it only had offline features, the most complex would be the local notification - but I need to add a GCM functionality to it. I searched for answers but it's so difficult to understand.
I tried to copy the code of a tutorial I've seen. I learned that I need a thing called GCMRegistrar but I don't know where to get it. Then I tested my app, there were errors of course because I don't have the gcmregistrar.
What I did is I enclosed the code in a comment block and ran the app again. That's when my app won't run anymore. After a few days of this mishap, I decided to create another app where I would put all the offline feature of my app. after that copying and pasting, I tried to run my the new app but it also won't run.
I've searched for ways to fix it and found a few fixes. Those fix works for other apps but won't work for my new app.
Here's my MainActivity.java, this one has the local notification
package com.example.mypower_build101;

I'm not putting everything here because it would be to lengthy and I think the problems might be at the MainActivity or the android manifest.
If you could teach me how use the gcm thing that would be very, very, much appreciated.
Hi guys for some reason my post have an error so please use and look at this document. here's the document link

We have a requirement to show an acknoldgement screen after user share some texts on Messaging apps such as Whatsapp, Telegram, SMS etc..
We have been using the react-native-share library for this and it works fine on non Huawei devices. However, Huawei devices doesn't return success/failure when user share hence the app gives issues on Huawei devices.
Upon checking the react-native-share library internal codes, it seems the BroadcastReceiver onReceive method does not get triggered when user choose and app on HuaweiChooser.
I created the following sample code to simulate this and on Non-Huawei devices this code's onReceive method get triggered but not in Huawei devices.
Appreciate any help regarding this.
This is the Sample code
MainActivity.java
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.content.IntentSender;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button shareButton = findViewById(R.id.button);
shareButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent chooser;
IntentSender intentSender = MyReceiver.getIntentSender(getApplicationContext());
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
sendIntent.setType("text/plain");
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP_MR1) {
chooser = Intent.createChooser(sendIntent,"Sharing Rocks",intentSender);
chooser.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
}else{
chooser = Intent.createChooser(sendIntent,"Sharing Rocks");
}
startActivityForResult(chooser, 1234);
}
});
}
}

context.registerReceiver(myReceiver, new IntentFilter(intentAction));
Intent intent = new Intent(intentAction);
intent.setPackage(context.getPackageName());
intent.putExtra(EXTRA_RECEIVER_TOKEN,myReceiver.hashCode());
PendingIntent callback = PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_CANCEL_CURRENT);
return callback.getIntentSender();
}

I change chooser title with "null" and my problem solved.
val chooser = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {
Intent.createChooser(sendIntent, null, pendingIntent.intentSender)
} else {
Intent.createChooser(sendIntent, null)

I am working on an app in react native. I am searching for a code when my app is in the background or has killed. I want a service like notifcationListnerService which invokes the app again. want a similar service that is always running and when a user copies something it will show a push notification to the user like that you have copied something.
Here is what I have tried but these are too complex to understand because these are in java.
Android ClipBoard Manager
Android ClipBoard With Example
This question from StackOverflow also does not have any answer
A solution for GitHub but too complex
one thing I didn't need #react-native-community/clipboard or something like this. the thing that I need is to show push notification on copying something for any app installed of the device.
So Finally searching for two days finally I have implemented what I want. I am showing a toast, not a notification(will implement it later). I am sharing my code but still, I have a problem when my application restart its service for clipboard manager the service is running as I see it in the logcat. Here is my code.
ClipboardMonitorService.java
package com.wm;
import android.app.Service;
import android.content.ClipData;
import android.content.ClipboardManager;
import android.content.Intent;
import android.os.Environment;
import android.os.IBinder;
import android.text.TextUtils;
import android.util.Log;
import android.widget.Toast;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.Date;
public class ClipboardMonitorService extends Service {
private static final String TAG = "ClipboardManager";
private static final String FILENAME = "clipboard-history.txt";
private File mHistoryFile;
private ExecutorService mThreadPool = Executors.newSingleThreadExecutor();
private ClipboardManager mClipboardManager;
#Override
public void onCreate() {
super.onCreate();
Log.e("service is running","service is running");
// TODO: Show an ongoing notification when this service is running.
mHistoryFile = new File(getExternalFilesDir(null), FILENAME);
mClipboardManager =
(ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
mClipboardManager.addPrimaryClipChangedListener(
mOnPrimaryClipChangedListener);
}
#Override
public void onDestroy() {
super.onDestroy();
if (mClipboardManager != null) {
mClipboardManager.removePrimaryClipChangedListener(
mOnPrimaryClipChangedListener);
}
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
private boolean isExternalStorageWritable() {
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state)) {
return true;
}
return false;
}
private ClipboardManager.OnPrimaryClipChangedListener mOnPrimaryClipChangedListener =
new ClipboardManager.OnPrimaryClipChangedListener() {
#Override
public void onPrimaryClipChanged() {
Log.d(TAG, "onPrimaryClipChanged");
ClipData clip = mClipboardManager.getPrimaryClip();
mThreadPool.execute(new WriteHistoryRunnable(clip.getItemAt(0).getText()));
Log.e("Copied Text","hahah"+clip.getItemAt(0).getText());
Toast.makeText(getApplicationContext(),"My App toast",Toast.LENGTH_SHORT).show();
}
};
private class WriteHistoryRunnable implements Runnable {
private final Date mNow;
private final CharSequence mTextToWrite;
public WriteHistoryRunnable(CharSequence text) {
mNow = new Date(System.currentTimeMillis());
mTextToWrite = text;
}
#Override
public void run() {
if (TextUtils.isEmpty(mTextToWrite)) {
// Don't write empty text to the file
return;
}
if (isExternalStorageWritable()) {
try {
Log.i(TAG, "Writing new clip to history:");
Log.i(TAG, mTextToWrite.toString());
BufferedWriter writer =
new BufferedWriter(new FileWriter(mHistoryFile, true));
writer.write(String.format("[%s]: ", mNow.toString()));
writer.write(mTextToWrite.toString());
writer.newLine();
writer.close();
} catch (IOException e) {
Log.w(TAG, String.format("Failed to open file %s for writing!",
mHistoryFile.getAbsoluteFile()));
}
} else {
Log.w(TAG, "External storage is not writable!");
}
}
}
}
This is used for when the app is closed or the device is restarted then it will start the service again.
BootUpRecever.java
package com.wm;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Build;
public class BootUpReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction() == Intent.ACTION_BOOT_COMPLETED){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
//log("Starting the service in >=26 Mode from a BroadcastReceiver")
context.startForegroundService(new Intent(context, ClipboardMonitorService.class));
return;
}
//log("Starting the service in < 26 Mode from a BroadcastReceiver")
context.startService(new Intent(context, ClipboardMonitorService.class));
}
}
}
to start the activity as the app start
MainActivity.java
package com.wm;
import android.content.Intent;
import android.os.Bundle;
import com.facebook.react.ReactActivity;
public class MainActivity extends ReactActivity {
#Override

}
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
// TODO: Show the contents of the clipboard history.
startService(new Intent(this, ClipboardMonitorService.class));
}
}
Here are the permissions and to start the service

I just started with Java and Android coding. I wrote an application for a scientific study in my university. The app is for a local exhibition of a museum. I have different locations in my town, each location with its own exhibit.
Now I made an activity for each of the locations, so the user can see some useful information of the sample. Now I want to combine the app with iBeacons, I bought 6 beacons from Estimote.
I want the app to give the user a notification with some text like: "You are in front of object XY. Tap to see more information." After tapping on the notification the user should open the specific activity which I created. I also want the app to search for beacons in the background, so if the user comes close to a location, he/she gets automatically a notification after a few seconds.
I already wrote some code but I don't know how to approach further. The application does nothing right now.
I did an extra class for the iBeacon stuff, in my MainActivity I have a menu in which the user can select a new activity, which is called "List Of Places". Then s/he can select the specific activity for each of the locations.
So here I have my beacon class:
package com.example.walter.him;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.app.Application;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.TaskStackBuilder;
import android.support.v4.app.NotificationCompat;
import org.altbeacon.beacon.BeaconConsumer;
import org.altbeacon.beacon.BeaconManager;
import org.altbeacon.beacon.BeaconParser;
import org.altbeacon.beacon.Identifier;
import org.altbeacon.beacon.Region;
import org.altbeacon.beacon.powersave.BackgroundPowerSaver;
import org.altbeacon.beacon.startup.RegionBootstrap;
import org.altbeacon.beacon.startup.BootstrapNotifier;
import java.util.Arrays;
import java.util.List;
public class BeaconMain extends Application implements BootstrapNotifier
{
private static final String TAG = "AndroidProximityReferenceApplication";
private RegionBootstrap regionBootstrap;
private BackgroundPowerSaver backgroundPowerSaver;
private boolean haveDetectedBeaconsSinceBoot = false;
private andreasplatz monitoringActivity = null;
private hagentor monitoringActivity2 = null;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate();
BeaconManager beaconManager = org.altbeacon.beacon.BeaconManager.getInstanceForApplication(this);
beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"));
beaconManager.bind((BeaconConsumer) this);
Region museumLocation1 = new Region("museumLocation1", Identifier.parse("B9407F30-F5F8-466E-AFF9-25556B57FE6D"), Identifier.parse("56170"), Identifier.parse("42307"));
Region museumLocation2 = new Region("museumLocation2", Identifier.parse("B9407F30-F5F8-466E-AFF9-25556B57FE6D"), Identifier.parse("55787"), Identifier.parse("12089"));
List regionList = Arrays.asList(new Region[]{museumLocation1, museumLocation2});
regionBootstrap = new RegionBootstrap(this, regionList);
backgroundPowerSaver = new BackgroundPowerSaver(this);
}
public void didEnterRegion(Region region) {
if (region.getUniqueId().equals("museumLocation1")) {
Intent intent = new Intent(this, andreasplatz.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
this.startActivity(intent);
}
if (region.getUniqueId().equals("museumLocation2")) {
Intent intent = new Intent(this, hagentor.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
this.startActivity(intent);
}
haveDetectedBeaconsSinceBoot = true;
}
#Override
public void didExitRegion(Region region) {
}
#Override
public void didDetermineStateForRegion(int i, Region region) {
}
private void sendNotification() {
NotificationCompat.Builder builder =
new NotificationCompat.Builder(this)
.setContentTitle("Beacon Reference Application")
.setContentText("An beacon is nearby.")
.setSmallIcon(R.drawable.ic_launcher);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addNextIntent(new Intent(this, andreasplatz.class));
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(
0,
PendingIntent.FLAG_UPDATE_CURRENT
);
builder.setContentIntent(resultPendingIntent);
NotificationManager notificationManager =
(NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(1, builder.build());
}
public void setMonitoringActivity(andreasplatz activity) {
this.monitoringActivity = activity;
}
}
The activity "andreasplatz" would be an exemplary location. The activity "hagentor" has the same code in it. So here is the code for it:
package com.example.walter.him;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.os.Bundle;
import org.altbeacon.beacon.BeaconManager;
public class andreasplatz extends Activity {
protected static final String TAG = "MonitoringActivity";
private BeaconManager beaconManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_andreasplatz);
verifyBluetooth();
}
private void verifyBluetooth() {
try {
if (!BeaconManager.getInstanceForApplication(this).checkAvailability()) {
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Bluetooth not enabled");
builder.setMessage("Please enable bluetooth in settings and restart this application.");
builder.setPositiveButton(android.R.string.ok, null);
builder.setOnDismissListener(new DialogInterface.OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog) {
finish();
System.exit(0);
}
});
builder.show();
}
}
catch (RuntimeException e) {
final AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Bluetooth LE not available");
builder.setMessage("Sorry, this device does not support Bluetooth LE.");
builder.setPositiveButton(android.R.string.ok, null);
builder.setOnDismissListener(new DialogInterface.OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog) {
finish();
System.exit(0);
}
});
builder.show();
}
}
}
What should I add or change, to do the app what I want? Here s an extract of my Manifest.xml - may be I did something wrong in it:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
android:versionCode="1"
android:versionName="1.0"
package="com.example.walter.him" >
<uses-sdk
android:minSdkVersion="18"
android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme"
android:launchMode="singleInstance" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
A few tips:
Since you are using the RegionBootstrap you do not need to make a call to bind to the beaconManager. Remove this line:
beaconManager.bind((BeaconConsumer) this);
Add debug lines to the top of your BeaconMain class' onCreate and didEnterRegion methods like this:
// put this at the top of onCreate
Log.d(TAG, "onCreate called");
// put this at the top of didEnterRegion
Log.d(TAG, "didEnterRegion called with: "+region..getUniqueId());
Make sure your beacons are transmitting those identifiers. Use an off the shelf beacon detector app like Locate when your beacons are turned on and make sure you see the same identifiers:
B9407F30-F5F8-466E-AFF9-25556B57FE6D 56170 42307
B9407F30-F5F8-466E-AFF9-25556B57FE6D 55787 12089
Once you have done the above, turn off your beacons, kill your app from the task switcher, re-launch your app, and turn on the beacons.
Watch the LogCat output and look for debug lines telling you if onCreate and didEnterRegion are called.
I am writing my own cordova plugin for Android. I have the plugin working inside a standalone Android project. I cannot seem to get my activity to start though from the plugin java file. It keeps firing errors that it cannot find MainActivity (cannot find symbol). I am hoping it is an easy fix that I seem to be missing.
Android Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.myapp.testplugin" >

public void initialize(CordovaInterface cordova, CordovaWebView webView) {
super.initialize(cordova, webView);
Log.d(TAG,"Init TestPlugin");
}
#Override

Context context = cordova.getActivity().getApplicationContext();
Intent intent = new Intent(context, MainActivity.class);
cordova.getActivity().startActivity(intent);
}
});
return true;
}
}
Error is occuring here:
Intent intent = new Intent(context, MainActivity.class);
I solved it this way:
Class mainActivity;
Context context = getApplicationContext();
String packageName = context.getPackageName();
Intent launchIntent = context.getPackageManager().getLaunchIntentForPackage(packageName);
String className = launchIntent.getComponent().getClassName();
try {
//loading the Main Activity to not import it in the plugin
mainActivity = Class.forName(className);
} catch (Exception e) {
e.printStackTrace();

I'm trying to develop a Geofence App for Android, that barely have to notify me when enter/exit/dwell in/from/into a Geofence.
Despite all questions and answers I red, I'm still not able to figure out my problem.
I think something is wrong with my PendinIntent and/or IntentService.
Here what I've done so far.
MainActivity.java
package it.coppola.geofencedetecttest1;
import android.app.Dialog;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class MainActivity extends ActionBarActivity implements
ConnectionCallbacks,OnConnectionFailedListener{
private GoogleApiClient mGoogleApiClient;
private GeofenceSampleReceiver mGeofenceReceiver;
private IntentFilter filter;
private Location mCurrentLocation;
private PendingIntent mPendingIntent;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mGoogleApiClient=new GoogleApiClient.Builder(this)

filter=new IntentFilter();
filter.addAction("it.coppola.geofencedetecttest1.ACTION_GEOFENCES_ERROR");
filter.addAction("it.coppola.geofencedetecttest1.ACTION_GEOFENCES_SUCCESS");
mGeofenceReceiver=new GeofenceSampleReceiver();
LocalBroadcastManager.getInstance(this).registerReceiver(mGeofenceReceiver, filter);
}
#Override

super.onResume();
LocalBroadcastManager.getInstance(this).registerReceiver(mGeofenceReceiver, filter);
}

lon.setText(String.valueOf(mCurrentLocation.getLongitude()));
Geofence mGeofence1=new Geofence.Builder()

.setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER|Geofence.GEOFENCE_TRANSITION_EXIT|Geofence.GEOFENCE_TRANSITION_DWELL)
.setExpirationDuration(Geofence.NEVER_EXPIRE)

.build();
mPendingIntent=requestPendingIntent();
GeofencingRequest mGeofenceRequest=new GeofencingRequest.Builder()
.addGeofence(mGeofence1)
.build();
LocationServices.GeofencingApi.addGeofences(mGoogleApiClient, mGeofenceRequest, mPendingIntent);
}
else {
}
}

#Override

String action = intent.getAction();
Log.d("miotag","ho ricevuto questo intent: "+action);
if (TextUtils.equals(action, "it.coppola.geofencedetecttest1.ACTION_GEOFENCES_ERROR")){
Log.d("miotag","ho ricevuto un errore dal Location Service");
}
else if (TextUtils.equals(action, "it.coppola.geofencedetecttest1.ACTION_GEOFENCES_SUCCESS")){
Log.d("miotag","intent ricevuto: OK");
}
}
}
private PendingIntent requestPendingIntent(){
if (null != mPendingIntent){
return mPendingIntent;
} else {
Intent intent=new Intent(this, GeofenceReceiverSample.class);
return PendingIntent.getService(
this,
0,
intent,
PendingIntent.FLAG_UPDATE_CURRENT);
}
}
public void stopIt(View v){
LocationServices.GeofencingApi.removeGeofences(mGoogleApiClient, mPendingIntent);
Log.d("miotag","geofence rimossa");
mGoogleApiClient.disconnect();
}
}
I've omitted some line of code not of interest.
here is my IntentService
package it.coppola.geofencedetecttest1;
import java.util.List;
import android.app.IntentService;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.support.v4.app.NotificationCompat;
import com.google.android.gms.location.Geofence;
import com.google.android.gms.location.GeofencingEvent;
public class GeofenceReceiverSample extends IntentService{
public GeofenceReceiverSample(){
super("GeofenceReceiverSample");
}
#Override
protected void onHandleIntent(Intent intent) {
GeofencingEvent geoEvent=GeofencingEvent.fromIntent(intent);
if (geoEvent.hasError()) {
//todo error process
} else {
int transitionType = geoEvent.getGeofenceTransition();
if (transitionType == Geofence.GEOFENCE_TRANSITION_ENTER ||
transitionType == Geofence.GEOFENCE_TRANSITION_EXIT) {
List<Geofence> triggerList = geoEvent.getTriggeringGeofences();
for (Geofence geofence : triggerList) {
generateNotification(geofence.getRequestId(), "address you defined");
}
}
}
}
private void generateNotification(String locationId, String address) {
long when = System.currentTimeMillis();
Intent notifyIntent = new Intent(this, MainActivity.class);
notifyIntent.putExtra("id", locationId);
notifyIntent.putExtra("address", address);
notifyIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notifyIntent, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder =
new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(locationId)
.setContentText(address)
.setContentIntent(pendingIntent)
.setAutoCancel(true)
.setDefaults(Notification.DEFAULT_SOUND)
.setWhen(when);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify((int) when, builder.build());
}
}
I've just pasted this IntentService from enter link description here, with few change.
Right now, I want to focus on IntentService and its handler: so at the moment I'm not asking for Broadcast Receiver that will be trigged from IntentService after the notification. This is why in my MainActivity there isn't any BroadcastReceiver class declared

Few more notes:
I really don't know why, but a couple of time the app actually works: my IntentService was fired up from Google Play Service intent and execute a previous version of the code. Weird enough, when I launchede again the same app without any change in the code, IntentService wasn't fired up.
I'm developing with my tablet/smartphone as emulator device: I tried to walk around but no luck at all.
Any help is highly appreciate.
Thanks.
Following the answer provided by ianhanniballake, I've done more tests with radius that space between 20-30-40 meters, and I found out that all works as intended. As he said, my problems was about the radius settings too small for GPS to recognize its own position.
Sincerely thanks.
