I found many topic but no case fit for my question.
The first my app working smooth, it is always startup with device by code bellow:
In AndroidManifest:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
and receiver:
<!-- start when module start broadcast -->
<receiver android:name=".StartOnBoot"
android:exported="true">
<intent-filter >
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<!-- listen messenger received -->
<receiver
android:name=".Phone.SmsListener"
android:exported="true">
<intent-filter android:priority="1000">
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
And class StartOnBoot
public class StartOnBoot extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){
Intent serviceIntent = new Intent(context, MainActivity.class);
serviceIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(serviceIntent);
}
} }
And now I added 2 broadcast to listen state of SD card and SIM card. But when I finish, My app can not start when my device restarted. And I don't know, where is problem, nothing clue.
<!-- broad cast SDCard receive-->
<receiver android:name=".Peripheral.SDCardListener">
<intent-filter>
<action android:name="android.intent.action.MEDIA_EJECT" />
<action android:name="android.intent.action.MEDIA_MOUNTED" />
<data android:scheme="file" />
</intent-filter>
</receiver>
<receiver android:name=".Phone.SimCardReceiver">
<intent-filter>
<action android:name="android.intent.action.SIM_STATE_CHANGED"/>
</intent-filter>
</receiver>
And 2 classes receiver:
public class SDCardListener extends BroadcastReceiver {
//restart app when SD card mounted
#Override
public void onReceive(Context context, Intent intent) {
Log.d("TAG","SDcard state : " + intent.getAction());
if (intent.getAction().equals(Intent.ACTION_MEDIA_EJECT)){
//sdcard eject
}else if (intent.getAction().equals(Intent.ACTION_MEDIA_MOUNTED)){
SDCard.getInstance().SDCardMounted();
}
}
}
for sim state:
public class SimCardReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Log.d("TAG", "Sim state :" + intent.getAction());
}
}
My device target is only Android 7.1, SDK lv 25.
Some methods I tried but not work:
I removed SimCardReceiver
I added "android:priortity to StartBoot" like this:
<intent-filter android:priority="1000">
But still not working, Remember, my app always work without 2 broadcast SDCardListener and SimCardReceiver
Extra question:
How many broadcast are available to use in one app. How many is good ? one or not limit
Could I merge all receiver to one broadcast

my program extends From BroadCastReciever to set Alarm, after the device is reboot receiver is not called, this is my code
1- BroadcastReceiver
public class myReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction()!=null) {
if (intent.getAction().equalsIgnoreCase("android.intent.action.BOOT_COMPLETED")) {
Log.d("myActivity","repooted");
// alarm settings
}
}
}

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

In your AndroidManifest.xml have you added permission to receive boot complete?
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
I have a several devices (Minix X68-i) all running the same firmware and software versions.
On some of them my boot receiver works fine, others it rarely works, and a few it's closer to 50-50 whether they will receive the event.
I'm out of ideas as to what could cause the code to work so erratically, other than potentially faulty hardware.
Manifest:
<receiver android:enabled="true" android:exported="true"
android:name="com.proreception.displaymanagement.Receiver.BootReceiver"
android:label="StartMyActivity" >
<intent-filter android:priority="500" >
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.QUICKBOOT_POWERON" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
BootReceiver
public class BootReceiver extends BroadcastReceiver {
private static final String TAG = "BootReceiver";
#Override
public void onReceive(Context context, Intent intent) {
if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction()) && constants.ONBOOT) {
Intent i = new Intent(context, FullscreenActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
Log.d(TAG, "Starting Application");
context.startActivity(i);
}
}
}
I want to do something that when I get the BOOT_COMPLETED,but now ,My application can't get the BOOT_COMPLETED.And my phone is the 4.0 sytem of Android.
Thanks!
Manifest
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
// if u want to start service
// <service android:name="com.example.afterbootservice.MyService" > </service>
<receiver android:name="YOUR PACKAGE NAME.BooteRecevier" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
Create BooteRecevier
public class BooteRecevier extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Intent service = new Intent(context,MyService.class);
context.startService(service);
// do what u want after boot in above to line i starting service when boot comple
}
}
I am developing a small android application in which I wanted to start some service once the device boot is completed.
This is the code I used to try to accomplish this, but it not receiving boot complete event, so it isn't working.
//in manifest file
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<receiver android:name="MyScheduleReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
//my schedule receiver
public class MyScheduleReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent)
{
if("android.intent.action.BOOT_COMPLETED".equals(intent.getAction()))
{
Log.i("*************************TEST", "Service loaded at start");
Toast.makeText(context, "device started", Toast.LENGTH_SHORT).show();
}
}
}
MyScheduleReceiver never gets triggered; am I doing something wrong?
You miss a dot before MyScheduleReceiver
<receiver android:name=".MyScheduleReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
Can anybody share the sample code to how to launch android application upon starting/booting up the device?
This code will launch an application on start up. You need to listen for ACTION_BOOT_COMPLETE.
in AndroidManifest.xml (application-part):
<receiver android:enabled="true" android:name=".BootUpReceiver"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
[..]
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
[..]
public class BootUpReceiver extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
Intent i = new Intent(context, MyActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
