android-broadcast

I want to register broadcast for low battery. If battery status reached at some level I want to get alert... Please if you have any idea please help me.. You will need to register a BroadcastReceiver for ACTION_BATTERY_LOW . You can do this in the manifest with a <receiver> element or via registerReceiver() from some already-running component of your application. For Battery_Status_Low, You could try registering it through a Service for example, like: BatteryReceiver receiver = new BatteryReceiver(); IntentFilter inf = new IntentFilter(); inf.addAction("android.intent.action.BATTERY_LOW");`

I am trying to get two apps to communicate via broadcasts. The first app sends a broadcast using code like the following: Intent outIntent = new Intent("org.example.WHATEVER"); PackageManager pm = this.getPackageManager(); List<ResolveInfo> receivers = pm.queryBroadcastReceivers(outIntent, 0); if (receivers != null) for (ResolveInfo receiver : receivers) { Log.d("Sender", String.format("Polling %s", receiver.activityInfo.packageName)); outIntent = new Intent("org.example.WHATEVER"); outIntent.setPackage(receiver.activityInfo.packageName); sendBroadcast(outIntent); } The receiving end registers

I'm new to Java / Android and trying to develop an adroid application which communicates with a USB CAN Bus adapter. I receive messages from the adapter in a string via my CANBusController class and I have built a parcelable class, CANMessage, which converts the string received into a form I can use (int Id, int Length, byte[] data). Now I'm trying to display the message I have received. I have a Fragment, CANBusControlFragment, which declares a BroadcastReceiver. When a message is a received, I build my CANMessage, place it and its string into a bundle, place the bundle into an Intent, and

I am trying to register a receiver programmatically to get notified once an NFC tag is detected. As shown in my code I registered for the desired action and I created the broadcast receiver programmatically. I also added the required permission in the manifest file but the problem is that onReceive is never called. Please let me know what I am doing wrong and how to fix it. IntentFilter intentFilter1 = new IntentFilter(); intentFilter1.addAction("android.nfc.action.TAG_DISCOVERED"); registerReceiver(mBCR_TAG_DISCOVERED, intentFilter1); private BroadcastReceiver mBCR_TAG_DISCOVERED = new

I have an Activity in which I am registering a BroadcastReceiver locally as follows: public class SomeActivity extends Activity{ public static final String PERFORM_SOME_ACTION = "PERFORM_SOME_ACTION"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.some_activity_layout); ..... ..... IntentFilter filter = new IntentFilter(); filter.addAction(PERFORM_SOME_ACTION); receiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { // perform some action ... } }; registerReceiver(receiver

I have a BroadcastReceiver and declared it like this: <receiver android:name="com.services.Receiver" android:enabled="true" android:exported="true" > <intent-filter android:priority="999" > <action android:name="android.intent.action.WALLPAPER_CHANGED" /> </intent-filter> </receiver> and the receiver is: @Override public void onReceive(final Context context, final Intent intent) { change_wallpepar.myPrefs = context.getSharedPreferences("myPrefs", Context.MODE_PRIVATE); new Handler().postDelayed(new Runnable() { @Override public void run() { Log.d("MAYUR", "<< wallpepar changed >>"); if (change
