Help Me...
"Implicit intent" warning that your are getting is because Using Implicit Intents you have not mentioned a specific component (for example: name of service class).
Implicit Intents does have not specified a component; instead, they must include enough information for the system to determine which of the available components is best to run for that intent.
So, it means the component will now be chosen by Android intent-filter mechanism, by given Intent-Action.
You may try following in code while starting a service:
Intent services = new Intent(context,MyService.class);//Explicit mention of service class name while creating intent
services.setAction("actions.com.sound_profile_change.MyService");
context.startService(services);
Above code is now using "explicit intent". Explicit Intents have specified a component which provides the exact class to be run.

I wrote my custom broadcast receiver to receive intents from my other app but it doesn't recieve anything. Im sure that first app is sending broadcast corectly. Can someone help me?
App1:
public void broadcastIntent() {
Intent intent = new Intent();
String permissions = "com.example.android.mybroadcastreceiver.my_permissions.MY_PERMISSION";
intent.putExtra("name", editName.getText().toString());
intent.putExtra("price", Float.parseFloat(editPrice.getText().toString()));
intent.putExtra("quantity", Integer.parseInt(editQuantity.getText().toString()));
intent.setAction("com.example.android.projekt1.notification");
sendBroadcast(intent, permissions);
}
And I run this function on my setOnClickListener method.
There is my broadcast receiver:
public class MyBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Intennt received.", Toast.LENGTH_LONG).show();
Intent serviceIntent = new Intent(context, MyService.class);
serviceIntent.putExtras(intent);
context.startService(serviceIntent);
}
}
So while sending broadcast I have 0 toast messages and my service doesn't run too.
There is androidManifest from receiver:
<?xml version="1.0" encoding="utf-8"?>
<permission-group android:name="com.example.android.mybroadcastreceiver.my_permissions"
android:label="my permissions group"/>
<permission android:name="com.example.android.mybroadcastreceiver.my_permissions.MY_PERMISSION"

<action android:name="android.intent.action.MAIN" />

<intent-filter>
<action android:name="com.example.android.projekt1.notification">
</action>
</intent-filter>
</receiver>
<service android:name="MyService" />
</application>
I run my receiver first then I run my main app and press the button to send broadcast
set package name of targeting application:
public void broadcastIntent() {
Intent intent = new Intent();
String permissions = "com.example.android.mybroadcastreceiver.my_permissions.MY_PERMISSION";
intent.putExtra("name", editName.getText().toString());
intent.putExtra("price", Float.parseFloat(editPrice.getText().toString()));
intent.putExtra("quantity", Integer.parseInt(editQuantity.getText().toString()));
intent.setAction("com.example.android.projekt1.notification");
intent.setPackage("Package name of receiver app");// set Package of targeting app
sendBroadcast(intent, permissions);
}
I'm working on an orange pi 2g IoT and BroadcastReceiver cannot start an activity or service on boot completed. When the app is running is can catch boot completed but it's not running as it cannot catch broadcasts.

You have very less execution time in Broadcast receivers if you want to get some more time you can use goAsync() like this.
#Override
public void onReceive(final Context context, final Intent intent) {
final PendingResult pendingResult = goAsync();
//some little long running task
pendingResult.finish();
}
Check this official doc for more details.
in you case it'd look like
#Override
public void onReceive(final Context context, final Intent intent) {
final PendingResult pendingResult = goAsync();
try{
Intent activityIntent = new Intent(context, MainActivity.class);
activityIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
Log.e("BC", "From BootCompled");
NotMan.ShowNotification(context,"From BootCompled:" + intent.getAction(),0 );
context.startActivity(activityIntent);
}
catch (Exception ex){Log.e("BC", ex.getMessage());}
pendingResult.finish();
}
I have an application A that has to bind to a service that is in another package. I have put a custom intent filter in order to make it work. Sadly the application wont bind. The log says that it can't find the service.
Application A is in the package "com.example.app_a"
The service is in another package "com.example.app_talker_service"
So I just can't refer to the service with the xxx.class solution, so my guess was to use an intent filter in the manifest file of the service's package.
Application A, on the other hand, will need to do a bind to the service to make it start (if it hasn't already started) and that later it will communicate with it though the use of broadcast receivers. I did some experimentation and I noticed that the broadcasts work fine, but what is wrond is that for some reason, the application A can't seem to find my service during the binding....
Here is the code for application A which binds in onStart():
#Override
protected void onStart()
{
// TODO Auto-generated method stub
super.onStart();
//Bind to service
getApplicationContext().bindService(new Intent("com.example.talker_service.SERVICE"), mConnection,Context.BIND_AUTO_CREATE);
}
private boolean mIsBound = false;
private ServiceConnection mConnection = new ServiceConnection()
{
#Override
public void onServiceConnected(ComponentName name, IBinder service) {
// TODO Auto-generated method stub
mIsBound = true;
Toast.makeText(getApplicationContext(), "CONNECTED TO SERVICE!", Toast.LENGTH_SHORT).show();
Intent intent = new Intent();
intent.setAction("com.example.talker_service.SERVICE");
intent.putExtra("REQUEST", "REGISTER APP");
intent.putExtra("FILTER", "com.example.app_a");
intent.putExtra("NAME", "Applicazione A");
String[] components = {"NUMBER_SENT","CHANGE_TEXT_COLOR","CHANGE_TEXTVIEW_SIZE"};
intent.putExtra("COMPONENTS", components);
MainActivityA.this.sendBroadcast(intent);
}
#Override
public void onServiceDisconnected(ComponentName name) {
// TODO Auto-generated method stub
mIsBound = false;
}
};
Here instead is the cmanifest for the service which I called Talker_service:
en<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.app_talker_service"
android:versionCode="1"

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
I don't undertsand why it doesn't bind.. I put the intent filter, am I missing something? Ah, and the logs says this:

This instead is the manifest file for application A

</intent-filter>
</activity>
</application>
</manifest>
I don't know why using intent filters is not working (it says that it can't find it) but by using the following code I was able to make my application connect to the remote service:
Intent i = new Intent();
i.setClassName("com.example.app_talker_service", "com.example.app_talker_service.Talker_Service");
bindService(i, conn, Context.BIND_AUTO_CREATE);
so using the seClassName method and providing the name of the pacake and that full path of the service, I was able to make it work. I am not sure if this falls in the realm of "best practice" for this type of problem, but for my it worked. Any solution is better than no solution. I found this solution thants to this link:
Remote Service Tutorial
I'm doing something I thought would be simple as have done a broadcast receiver in the past on 2.3.4 droid. I'm using 4.x now in this little program.
Here is the main architecture/flow. I want/have a receiver to be listening for a custom broadcast/intent. I created this as a stand along project/apk
public class FileIntegrityMonitor extends BroadcastReceiver
{
public String CLASS_NAME = "FileIntegrityMonitor";
#Override
public void onReceive(Context context, Intent intent)
{
Log.d(CLASS_NAME, "Entered onReceive: got broadcast from startFIM");
String actionReceived = intent.getAction();
Log.d(CLASS_NAME, "Action received=" + actionReceived);
if (actionReceived.equals(StartFIMActivity.CUSTOM_INTENT))
{
//start service to perform the file integrity check
Log.d(CLASS_NAME, "start service to perform file integrity check");
}
}
Then I created a activity as a separate project/app as a driver for now to kick the broadcast receiver off. Will probably replace with something else later but wanted to get the mechanics/comms down now.
public class StartFIMActivity extends Activity
{
/** Called when the activity is first created. */
public static final String CUSTOM_INTENT = "com.kdms2.StartFIM.intent.action.start";
public String CLASS_NAME = "StartFIMActivity";
#Override
public void onCreate(Bundle savedInstanceState)
{
Log.d(CLASS_NAME, "Entered onCreate");
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent i = new Intent();
i.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES); //api 3.1+
i.setAction(CUSTOM_INTENT);
Log.d(CLASS_NAME, "send brodcast to monitor");
this.sendBroadcast(i);
}
}
Now in the trace I do get the intent in FileIntegrityMonitor but a strange message that it's trying to run some method and I don't know why. Error is:
E/AndroidRuntime(979): java.lang.RuntimeException: Unable to instantiate receiver com.kdms2.FileIntegrityMonitor.StartFIMActivity: java.lang.ClassNotFoundException: com.kdms2.FileIntegrityMonitor.StartFIMActivity
why did it add the class name of the activity that broadcast the action to the broadcast receiver?
Is it something in the manifest (receiver)?
<uses-sdk android:minSdkVersion="10" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<receiver android:name=".StartFIMActivity" android:enabled="true">
<intent-filter android:priority="99999999999">
<action android:name="com.kdms2.StartFIM.intent.action.start"/>
</intent-filter>
</receiver>
</application>
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
</manifest>
activity manifest
<uses-sdk android:minSdkVersion="10" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".StartFIMActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
</application>
</manifest>
v/r,
Frank
Your receiver's name is FileIntegrityMonitor, but in the manifest you try to register StartFIMActivity as both the <activity> and <receiver> elements. Probably oughta be:
<receiver android:name=".FileIntegrityMonitor" android:enabled="true">
<intent-filter android:priority="99999999999">
<action android:name="com.kdms2.StartFIM.intent.action.start"/>
</intent-filter>
</receiver>
Or something of the like.
HTH
I try to get a broadcast receiver working. Should be as simple as possible, I have my manifest like this:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mytest.intentRec" android:versionCode="1"
android:versionName="1.0">
<application android:icon="#drawable/icon" android:label="#string/app_name"
android:debuggable="true">
<activity android:name=".mainAct" android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="com.mytest.intentRec.MyIntentRec"
android:enabled="true" >
</receiver>
</application>
<uses-sdk android:minSdkVersion="7" />
</manifest>
As you can see I have a main activity mainAct, this does nothing but sending the broadcast once started:
public class mainAct extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this.sendBroadcast(new Intent());
}
}
and I have a class MyIntentRec, which is as simple as it could:
public class MyIntentRec extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.v("IntentRec", "got it");
}
}
What I expect is that when I start my app that a broadcast is sent and being picked up and that a log entry is written. I don't see that log entry and I don't see any error. I'm suspecting to have either an error in the manifest or in sending the broadcast. I just created an empty intent there, does it need to be some intent with certain properties?
Please setClass for your Intent,
EX:
public class mainAct extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent i=new Intent("any string");
i.setClass(this, MyIntentRec.class);
this.sendBroadcast(i);
}
}
That is what it means " The absence of any filters means that it can be invoked only by Intent objects that specify its exact class name."
[Old answer]
You should register what kind of actions you need in the manifest.
Ex:
<receiver android:name="com.mytest.intentRec.MyIntentRec" android:enabled="true" >
<intent-filter>
<action android:name="your.intent" />
</intent-filter>
</receiver>
send it,
this.sendBroadcast(new Intent("your.intent"));
it is insufficient to make just new Intent();. You have to specify it with some action. Also, you have to specify in your manifest the intent filter for this particular action. Please read more here and here.
You didn't define any Intent Filters in the manifest for your BroadcastReceiver. Specify one for a custom Action type. You also have to define this custom Action type in the Intent you brodcast upon startup.
Try specifying what actions your receiver should catch in the manifest. You can do this as such:
<receiver android:name="com.mytest.intentRec.MyIntentRec">
<intent-filter>
<action android:name="android.intent.action.MEDIA_BUTTON" />
</intent-filter>
</receiver>
