I am developing a calendar widget, and I can't receive the DATE_CHANGED message when I changed the date MANUALLY.
What is the problem?
My code in Manifest is :
<receiver android:name="com.widget.calendar.CalendarWidgetProvider">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
<action android:name="android.intent.action.DATE_CHANGED"/>
</intent-filter>
<!-- This specifies the widget provider info -->
<meta-data android:name="android.appwidget.provider"
android:resource="#xml/widgetinfo" />
</receiver>
And I tried to receive it like this:
#Override
public void onReceive(Context ctx, Intent intent) {
final String action = intent.getAction();
if (action.equalsIgnoreCase("android.intent.action.DATE_CHANGED")) {
Log.e(TAG, "Date changed.....!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
}
super.onReceive(ctx, intent);
}
But the log is not print when I change the system date manually.
Thanks!
UPDATE:
I solved this with Intent.ACTION_TIME_CHANGED, It's really a bug of DATE_CHANGED.
Use this intent:
<intent-filter>
<action android:name="android.intent.action.TIME_SET"/>
</intent-filter>
And receive:
#Override
public void onReceive(Context ctx, Intent intent) {
final String action = intent.getAction();
if (action.equalsIgnoreCase("android.intent.action.TIME_SET")) {
Log.e(TAG, "Date changed.....!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
}
super.onReceive(ctx, intent);
}

I want to develop app that doesn't have icon launcher. The app will run alarmscheduler which triggered when app is installed or phone is rebooted.
The problem is how can I open the activity since the app doesn't have intent filter like below:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
Is there a way to handle dial code such as ##4635*#*# to open the activity ?
or any other solutions are welcomed.
You can do it with two ways:
1) as answer by #KishuDroid
2) By define code in manifest
public class MySecretCodeReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equals("android.provider.Telephony.SECRET_CODE")) {
Intent i = new Intent(context, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
}
In manifest file
<receiver android:name=".MySecretCodeReceiver">
<intent-filter>
<action android:name="android.provider.Telephony.SECRET_CODE" />
<data android:scheme="android_secret_code" android:host="4635" />
</intent-filter>
</receiver>
Note:
In Second method you must have to dial *#*#your_code#*#* and dont need to press call button
But in first method you can customise your prefix or postfix of code. For example *#your_code# or **your_code##. but you need to press call button.
You have to use Broadcast Receiver...
public class OutgoingCallReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Bundle bundle = intent.getExtras();
if(null == bundle)
return;
String phonenumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Log.i("OutgoingCallReceiver",phonenumber);
Log.i("OutgoingCallReceiver",bundle.toString());
if(code.equals("#056700") {
intent.setComponent(new ComponentName("com.example", "com.example.yourActivity"));
And Your Android Manifest
<receiver android:name="com.varma.samples.detectcalls.receivers.OutgoingCallReceiver">
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL"/>
</intent-filter>
</receiver>
Also, include the permission:
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
I want to write a BroadcastReceiver to receive the application install action. But it failed, so I test if my receiver is well or not. So custom a intent, it also filed. below is my code. Please help me correct it.
public class MyInstallReceiver extends BroadcastReceiver {
// public MyInstallReceiver() {
// }
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Intent Detected.", Toast.LENGTH_LONG).show();
Log.d("receiver", "Intent Detected");
if (intent.getAction (). equals ("android.intent.action.PACKAGE_ADDED")) {
String packageName = intent.getDataString ();
//System.out.println ("installed:" + packageName + "package name of the program");
Log.d("receiver","installed:" + packageName + "package name of the program");
}
}
}
custom intent
public void installAPK(View v){
startActivity(intent);
Intent intent = new Intent();
intent.setAction("com.tutorialspoint.CUSTOM_INTENT");
sendBroadcast(intent);
Log.d("receiver", "Intent sent");
}
Manifest.xml
<receiver
android:name=".MyInstallReceiver"
android:enabled="true"
android:exported="true" >
<Intent-filter>
<action android:name = "android.intent.action.PACKAGE_ADDED"/>
<action android:name = "android.intent.action.PACKAGE_REMOVED"/>
<action android:name="com.tutorialspoint.CUSTOM_INTENT">
</action>
<Data android:scheme = "package" />
</Intent-filter>
</receiver>
enter code here
I don't know about correct spelling in your manifest, but this code is definitely works very well:
<receiver android:name=".MyInstallReceiver">
<intent-filter>
<action android:name="android.intent.action.PACKAGE_REMOVED" />
<action android:name="android.intent.action.PACKAGE_ADDED" />
<data android:scheme="package"/>
</intent-filter>
</receiver>
Every application install/uninstall will trigger this receiver.
Everythong looks good, expect a typo in your manifest. It should be <intent-filter> and not <Intent-filter>
I found lots of threads about this topic, however I'm not able to solve my problem. Here is the code:
The manifest file:
<service
android:name="com.xxx.player.MediaPlayerService.MediaPlayerService"
android:enabled="true" >
<intent-filter>
<action android:name="android.media.AUDIO_BECOMING_NOISY" />
</intent-filter>
<receiver android:name="com.xxx.player.MediaPlayerService.MediaPlayerService$ServiceBroadcastReceiver"
android:enabled="true"
android:exported="false">
<intent-filter>
<action android:name="#string/ACTION_PREPARE_AND_PLAY_NEW_FILE"/>
<action android:name="#string/ACTION_PREPARE_NEW_FILE"/>
<action android:name="#string/ACTION_START"/>
<action android:name="#string/ACTION_STOP"/>
<action android:name="#string/ACTION_PAUSE"/>
<action android:name="#string/ACTION_SEEK_TO"/>
<action android:name="#string/ACTION_RELEASE"/>
</intent-filter>
</receiver>
</service>
The broadcast class:
public class MediaPlayerService extends Service implements
MediaPlayer.OnErrorListener,
AudioManager.OnAudioFocusChangeListener,
Runnable,
SeekBar.OnSeekBarChangeListener {
...
public class ServiceBroadcastReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
Toast.makeText(getApplicationContext(), "action: " + action, 30000000).show();
if (action.equals(Resources.getSystem().getString(R.string.ACTION_PREPARE_AND_PLAY_NEW_FILE))) {
prepareAndPlayNewFile(intent.getStringExtra("mediaData"));
}
}
}
}
The way I submit the intent:
private void prepareAndPlayNewFile(String mediaData) {
Intent myIntent = new Intent();
myIntent.setAction(context.getString(R.string.ACTION_PREPARE_AND_PLAY_NEW_FILE));
myIntent.putExtra("mediaData", mediaData);
context.sendBroadcast(myIntent);
}
Instead of approaching your playing of media this way, you should instead bind your Service to your Activity instead of using a broadcast receiver for message passing.
Also you shouldn't be using #string/VAR1 (which I'm not sure if intent filters work with that kind of string definition) for your intent actions it ALWAYS should be the constant string such as:
android.intent.action.BLAH
This is how I am setting the priority of my application intent filter highest.After receiving the intent Extras I abort the broadcast, but the native app is still receiving the sms and notification bar is still showing the message content which is most annoying as I dont want it to show message body. Is there something I am missing??
<receiver android:name=".MySmsReceiver" >
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED"
android:priority="999"
/>
</intent-filter>
</receiver>
this is my receiver's onReceive() method
public void onReceive(final Context context, Intent intent) {
Bundle extras = intent.getExtras();
abortBroadcast();
....
}
Try to declare your receiver in this way :
<receiver android:name=".MySmsReceiver">
<intent-filter android:priority="999">
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
Instead of :
<receiver android:name=".MySmsReceiver" >
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED"
android:priority="999"
/>
</intent-filter>
</receiver>
Also try to check the following condition before aborting your broadcast :
EDITED :
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(SMS_RECEIVED)) {
Bundle extras = intent.getExtras();
if(extras != null)
// doBroadcast();
else
abortBroadcast();
}
}
Hope it helps you.
Thanks.
I am new to android ,how can I know if the call button is pressed or i can replace default dialer activity using my dialer I have used following code
