I want to notify when power of the phone connects and disconnects by broadcast receiver.
but the problem is that it doesnt work when i define receiver in manifest, but it works well if i defineit dynamically.
This is my manifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.example.batterymanager">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme"
tools:ignore="GoogleAppIndexingWarning">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".PowerConnectionReceiver">
<intent-filter>
<action android:name="android.intent.action.ACTION_POWER_CONNECTED"/>
<action android:name="android.intent.action.ACTION_POWER_DISCONNECTED"/>
</intent-filter>
</receiver>
</application>
</manifest>
And here is my Broadcast:
package com.example.batterymanager;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;
public class PowerConnectionReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
/*if (intent.getAction().equals("android.intent.action.ACTION_POWER_CONNECTED")) {
Toast.makeText(context, "Power Connected", Toast.LENGTH_SHORT).show();
} else if (intent.getAction().equals("android.intent.action.ACTION_POWER_DISCONNECTED")){
Toast.makeText(context, "Power Disconnected", Toast.LENGTH_SHORT).show();
}*/
Toast.makeText(context, "" + intent.getAction(), Toast.LENGTH_SHORT).show();
Log.i("HUU", intent.getAction());
}
}
I dont know why it doesnt work! ):
New android limitations:
As part of the Android 8.0 (API level 26) Background Execution Limits,
apps that target the API level 26 or higher can no longer register
broadcast receivers for implicit broadcasts in their manifest.
However, several broadcasts are currently exempted from these
limitations. Apps can continue to register listeners for the following
broadcasts, no matter what API level the apps target.

I am writing an application running on my custom device (marshmallow based). the general idea is to prompt a user dialog to enter some information at boot and send it to my server. once the information is successfully sent I update the shared preferences that the information was sent and the dialog will not be prompt anymore.
as always I check to see if the needed permissions are present (read phone state for IMEI and sim info), if not I create an activity that requests permissions and on result starts the user dialog activity. if permissions already exist I create the dialog activity straight from the boot receiver.
however, for some reason, sometimes the permissions activity is created twice (I made sure the boot receiver is only triggered once). this causes as expected the user dialog to be shown twice for no reason. does anyone know how can I solve this? thank you.
here is a code snippet for the boot receiver (the only place where the permissions activity is started).
public class BootReceiver extends BroadcastReceiver {
SharedPreferences mPrefs;
boolean wasUpdated;
#Override
public void onReceive(Context context, Intent intent) {
Log.v("car_num", "got boot receiver");
mPrefs = context.getSharedPreferences("car_num", MODE_PRIVATE);
wasUpdated = mPrefs.getBoolean("is_num_updated", false);
if (!wasUpdated) {
Log.v("car_num", "first time - asking for car num");
if (UtilityFunctions.checkPermission(context, Manifest.permission.READ_PHONE_STATE)) {
Log.v("car_num", "we have permission lets ask for car num");
Intent i = new Intent();
i.setClassName("com.mgroup.carnumberapp", "com.mgroup.carnumberapp.MainActivity");
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
Log.v("car_num", "main activity started");
} else {
Log.v("car_num", "no permission - so requesting");
Intent i = new Intent();
i.setClassName("com.mgroup.carnumberapp", "com.mgroup.carnumberapp.PermissionActivity");
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.putExtra("from", "boot receiver");
context.startActivity(i);
}
} else {
Log.v("car_num", "car number already updated - doing nothing");
}
}
}
edit:
I tried adding
android:launchMode = "singleTop"
however, it happened again.
here is my manifest :
<?xml version="1.0" encoding="utf-8"?>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<application
android:allowBackup="true"

android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/MGServiceTheme">
<service
android:name=".SendDetailsService"
android:enabled="true"
android:exported="true"></service>
<activity android:name=".PermissionActivity"
android:launchMode = "singleTop"/>
<receiver
android:name=".BootReceiver"
android:enabled="true"
android:exported="true">

<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>

<intent-filter>
<action
android:name="android.intent.action.MAIN"
android:theme="#style/Theme.AppCompat.NoActionBar" />
</intent-filter>
</activity>
</application>
In your manifest do android:launchMode="singleTop" for an activity
like
<activity android:name=".MapActivity"
android:launchMode="singleTop"/>
<activity android:name=".MainActivity"
android:launchMode="singleTop">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
I created a basic app to check whether broadcast is received when phone state is changed, but it is not working. I tried with making outgoing call and incoming calls too. I realized these are common issues with Vivo, Honor etc. Here is Manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="jss.servicetester">
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".ReceiverMe">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
</application>
</manifest>
And here is code for receiver:
package jss.servicetester;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
/**
* Created by DELL WORLD on 5/28/2017.
*/
public class ReceiverMe extends BroadcastReceiver {
String LOGTAG = "Receiver";
#Override
public void onReceive(Context context, Intent intent) {
Log.d(LOGTAG, "action:" + intent.getAction());
}
}
Can anyone help me.
started working in oppo F3 after making some changes in battery options for application. Like Unfreeze app in background.
I have written below code in Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="jss.battery">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver
android:name=".BatteryReceiver">
<intent-filter >
<action android:name="android.intent.action.ACTION_POWER_CONNECTED"/>
</intent-filter>
</receiver>
</application>
</manifest>
and below is code for receiver:
public class BatteryReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Broadcast received", Toast.LENGTH_LONG).show();}}
But I m not getting any Toast on App launch. and here is code for mainactivity:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity);
}
}
Is there any error in code? I read many pages with similar issue here but none of solution worked. Also referred https://developer.android.com/training/monitoring-device-state/battery-monitoring.html#DetermineChargeState .At Testing time battery level is 80% +.
Quoting the documentation, this broadcast "will be sent after ACTION_BATTERY_LOW once the battery has gone back up to an okay state". In your case, the battery is already at 80%, which is well past the low/okay dividing line (which I think is around 15%, but might vary by hardware or OS version).
I am attempting to migrate an app from Parse to OneSignal. Things have been running fairly smooth except for one issue. If the app has not already been started, clicking (opening) the notification does not launch the app and bring it to the foreground.
I am using a custom onNotificationOpenedHandler:
Main Activity, onCreate
// Init OneSignal
OneSignal.startInit(this).setNotificationOpenedHandler(new NotificationOpenHandler()).init();
NotificationOpenedHandler, also in the launcher Main Activity:
class NotificationOpenHandler implements OneSignal.NotificationOpenedHandler {
// This fires when a notification is opened by tapping on it.
#Override
public void notificationOpened(OSNotificationOpenResult result) {
JSONObject data = result.notification.payload.additionalData;
String stationName = data.optString("stationName");
String timestamp = data.optString("timestamp");
String filename = data.optString("filename");
String url = getString(R.string.callResourceUrl) + filename;
Log.d("APP", "Notification clicked");
Intent intent = new Intent(getApplicationContext(), CallActivity.class);
intent.putExtra("stationName", stationName);
intent.putExtra("time", timestamp);
intent.putExtra("url", url);
intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
}
}
Here is my Android Manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.opheliadesign.tevfd">
<uses-permission android:name="android.permission.INTERNET" />

<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".CallActivity"
android:label="#string/title_activity_call"
android:parentActivityName=".MainActivity"
android:screenOrientation="portrait" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.app.MainActivity" />
</activity>
<meta-data android:name="com.onesignal.NotificationOpened.DEFAULT" android:value="DISABLE" />
</application>
</manifest>
Any ideas?
UPDATE
Previously, using Parse, I utilized a BroadcastReceiver with a PendingIntent. It seems a bit unclear how to accomplish this with OneSignal as so much seems to be configured automatically.
If I remove the custom Intent, the application comes to the foreground.
Any help would be greatly appreciated.
My question will be seem's stupid but I make a simple code to make a Toast when I receive a SMS, but impossible to see my toast.
My Android Manifest :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.romain.assistantvocal" >
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
<receiver class="com.example.romain.SMSReceiver" android:name=".SMSReceiver">
<intent-filter android:priority="100">
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
<activity
android:name=".MyActivity"
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 class="com.example.romain.SMSReceiver" android:name=".SMSReceiver">
<intent-filter android:priority="100">
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
</application>
And here my class SMSReceiver :
package com.example.romain.assistantvocal;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.telephony.gsm.SmsMessage;
import android.widget.Toast;
import java.util.Locale;
/**

*/
public class SMSReceiver extends BroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent)
{
Toast.makeText(context,"gg romstan",Toast.LENGTH_LONG).show();
}
}
Thank you in advance for your answers.
Try using this revicer:
<receiver android:name=".SmsReceiver" android:permission="android.permission.BROADCAST_SMS" android:exported="true">
<intent-filter android:priority="6565" >
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
replace
<receiver class="com.example.romain.SMSReceiver" android:name=".SMSReceiver">
with
<receiver android:name="com.example.romain.assistantvocal.SMSReceiver">
If ur aware of Ordered broadcasts then it says "As each receiver executes in turn, it can propagate a result to the next receiver, or it can completely abort the broadcast so that it won't be passed to other receivers. "
So. If any broadcast has stopped passing data, u won't get the message.
Try putting log in ur receiver and check. Whether ur receive message or not because ur toast message is correct.
U can't keep priority more than 1000 as per android guidelines. so, give some thing near to 1000 or remove priority and check.
