I am new to android development, and
I have an app that when run from the app icon in the menu / home screens runs just fine. However when I try to make it run on boot completion it crashes (Keeping in mind that if I go back to the Icon it will still work) I am wondering what is wrong here. Keep in mind I am doing testing on my personal phone which is android 2.3 and it is ROOTED. Some how I don't think this should be as hard as it is to do, since 9/10 most android apps work in this way or in a way similar to this. Simply put: What am I doing wrong?
In the mean time here is my code for the Broadcast Receiver:
package path.to.file;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class autoBot extends BroadcastReceiver {
private static final String LOG_TAG = "StartAtBootServiceReceiver";
#Override
public void onReceive(Context context, Intent intent) {
Log.e(LOG_TAG, "onReceive:");
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
Intent i = new Intent();
i.setAction("path.to.file.MainActivity");
context.startActivity(i);
}
}
}
As well as the Manifest file:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
installlocation="internalOnly"
package="path.to.file"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="autoBot" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" >
</action>
<category android:name="android.intent.category.HOME" >
</category>
</intent-filter>
</receiver>
</application>
</manifest>
Is there a specific reason you are adding an action to your intent? If your only aim is to launch your activity at start-up, do this in your BroadcastReceiver:
Intent i = new Intent(context, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
Also, remove these lines from your manifest under receiver tag, you won't need them there:
<category android:name="android.intent.category.HOME" ></category>

I've seen a lot of question like this around and I've tried a bunch of things without success...
I just want to log a sms received using a subclass of BroadcastReceiver like I've seen in so many tutorial...
so here is my code and config
BroadcastReceiver
package com.example.koki.mysms;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;
public class SmsReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.d("MainActivity", "test");
Toast.makeText(context, "ON RECEIVE BROADCAST", Toast.LENGTH_LONG).show();
}
}
there's nothing in my MainActivity beside what you get when creating a new projet with android studio.
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.koki.mysms" >
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.SEND_SMS" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.WRITE_SMS" />
<application

</intent-filter>
</activity>
<receiver android:name=".SmsReceiver" android:exported="true">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
</application>
</manifest>
the way I test it (not very familiar in android development yet), is that I have two emulator and I sent sms to one another. They both receive the sms but nothing in the logcat nor the Toast appear. what am I doing wrong?
Hello fellow programmers,
I cant find a proper way to route my application, I would like one file to decide which activity has to be started
I am building an android application that in general contains:
-2 ways to start up
-3 activity's
The application can be launched by clicking the icon (standard launch)
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
And an activity is started when there is an incoming call
<action android:name="android.intent.action.PHONE_STATE" />
In the first setup there was 2 activity's one to register and one to use the application. In this
setup I added an extra activity to check if a token was present and route to the right activity.
In the setup that I have now, all the actions are in the of a broadcast receiver. I tried implementing the logic of the extra activity.
The problem I am facing is the check of the incoming call, it is always launching the same activity CallHandler,
I think routing the application within a broadcast receiver might be bad practice, but I can not find a better way of routing the application, and the current code does not work.
Your help is very much appreciated, the following pieces of code might help explain my issue:
Manifest:
<?xml version="1.0" encoding="utf-8"?>
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.READ_PROFILE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<receiver android:name=".RoutingCallReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</receiver>
<activity
android:name=".RegisterActivity"
android:label="#string/app_name"
android:windowSoftInputMode="adjustResize|stateVisible" >
</activity>
<activity
android:name=".CallHandler"
android:label="#string/title_activity_main" >
</activity>
<activity
android:name=".CreateCallActivity"
android:label="#string/title_activity_create_call" >
</activity>
</application>
RoutingCallReceiver:
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
public class RoutingCallReceiver extends BroadcastReceiver {
TelephonyManager telephony;
Intent in;
public void onReceive(Context context, Intent intent) {
PrimePhoneStateListener phoneListener = new PrimePhoneStateListener();
telephony = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
telephony.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE);
if(telephony.getCallState()== 1){
in = new Intent(context, CallHandler.class);
in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(in);
}
else {
TokenIO tokenHandler = new TokenIO();
String token = tokenHandler.getToken(context);
Log.d("AAfter", "Token");
if(token.equals("") || token.equals(null)){
in = new Intent(context, RegisterActivity.class);
in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(in);
}
else{
in = new Intent(context, CreateCallActivity.class);
in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(in);
}
}
}
// when finish your job, stop listen to changes
public void onDestroy() {
telephony.listen(null, PhoneStateListener.LISTEN_NONE);
}
}
you can make change in your xml file
<?xml version="1.0" encoding="utf-8"?>
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.READ_PROFILE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<receiver android:name=".RoutingCallReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
<activity
android:name=".RegisterActivity"
android:label="#string/app_name"
android:windowSoftInputMode="adjustResize|stateVisible" >
</activity>
<activity
android:name=".CallHandler"
android:label="#string/title_activity_main" >
</activity>
<activity
android:name=".CreateCallActivity"
android:label="#string/title_activity_create_call" >
</activity>
</application>
and put this tag into main activity
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
and i hope that will work fine.
i'm having trouble with the auto-start feature of my APP.
I've searched trhough the forums, seen many suggestions, none seems to work and I don't know why.
Here's the BootUpReciver.java
package com.???.???;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;
public class BootUpReciver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
//Intent pushIntent = new Intent(context, BackgroundService.class);
//context.startService(pushIntent);
Toast.makeText(context, "Device Booted", Toast.LENGTH_LONG).show();
Log.d("TAG","Device Booted");
}
}
}
And here's my Manifest file
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.???.???"
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="android.permission.VIBRATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="17" />
<application
android:theme="#android:style/Theme.Holo"
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<receiver android:name=".BootUpReciver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
<activity
android:name="com.???.???.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>
</application>
When i restart my phone i don't even see the Toast, why? what should i do? I need to auto-start to get some sharedprefs and write a value to a file every boot.
Thanks.
While testing I found that If I show toast in onReceive then it is not showing. But if I start an activity in onReceive then it is working. So you can also check this. Start an activity or service and perform your task there.
I am trying to get my app to auto start on boot up and it will and an error occurs while launching the application
Here is my manifest and the program file for the "Auto Starter":
manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="this.bad.file"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver
android:name="autoBot"
android:enabled="true"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>
</manifest>
Here is the "AutoBot" as I have called it (Not for spammy reasons I just like transformers):
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class autoBot extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
Intent startUp = new Intent(context, MainActivity.class);
context.startActivity(startUp);
}
}
So there we have it!
In your manifest, you left out a vital name of the class, usually, can be abbreviated to [dot][ClassName] or the full package name, as in for example .autoBot or see the example below:
<receiver android:name="this.bad.file.autoBot">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
And in your Broadcast receiver:
public class autoBot extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent startUp = new Intent(context, MainActivity.class);
context.startActivity(startUp);
}
}
Notice the usage of #Override on the onReceive class.
The normal recommended route to take is usually, to start an alarm on boot, and listen for the broadcast when the alarm has expired, in that way your activity does not hog up the boot and also, allow the boot up process to "settle" for a bit.
I have been trying to use the BroadcastReceiver on ICS from a while now.
I have tried all kinds of solutions, but nothing worked for me.
Here is how my manifest file looks like...
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.sp.android"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".XYZActivity"
android:label="#string/app_name"
android:windowSoftInputMode="adjustResize" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".ScreenOffReceiver">
<intent-filter>
<action android:name="android.intent.action.SCREEN_OFF" />
</intent-filter>
</receiver>
</application>
</manifest>
And here is my Receiver code...
package com.sp.android;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class ScreenOffReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context arg0, Intent arg1) {
Log.e("AppSearch", "Message");
}
}
The activity class has some code in it. But now this broadcast receiver never gets registered it seems. The onReceive() method does not get called. I could not find any solution. All the threads mentioned that I need to have at least one activity, but I already have it.
Thank you in advance!
You also need to start the activity (via the launcher) at least once, otherwise your app will be in a 'stopped' stated, and won't receive any broadcasts.
