I try to launch a service at boot, but it never starts the service. I added <action android:name="android.intent.action.ACTION_POWER_CONNECTED"/> to the intent-filter of the receiver, but when I connect my android 8.0 phone to power, it also doesn't work.

Intent i = new Intent(context, MainService.class);
context.startService(i);
}
}
MainService:
public class MainService extends Service {
public static boolean isRunning = false;
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
isRunning = true;
Toast.makeText(this, "Service started", Toast.LENGTH_LONG).show();

}
#Override

}
public void connected() {
//things to do when it has wifi connection
}
}
In my MainActivity class, I start this service using the same way as in my StartAtBoot class, and there it works fine when I open the application. So the service is working fine, its just that the StartAtBoot class doesn't run the code.
ACTION_POWER_CONNECTED is not a listed exception to the limits on implicit Intent broadcasts. Your app cannot register for it in the manifest.
If your goal is to do work periodically, but only if the device has power, use JobScheduler or WorkManager.

In my application there are two receivers, one receives calls (MyReceiverCall) and the second SMS (MyReceiverSms).
When you start the app everything works fine, I get a notification when I receive an SMS or call.
But if I close the app in task Manager then nothing wants to work and all incoming SMS and calls are ignored by the receiver.
I had assumptions that can be simply service with my notification does not start, but through logs I understood that the receiver simply does not work. (But so far the assumption is that services are to blame)
My code
MyReceiverCall.class
public class MyReceiverCall extends BroadcastReceiver {
private static final String ACTION = "android.intent.action.PHONE_STATE";
#Override
public void onReceive(Context context, Intent intent) {
Log.i("123","sakuraso13 ReceiverCall");
if (intent != null && intent.getAction() != null) {
if (intent.getAction().equals(ACTION)) {
String number=intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_RINGING) & number!=null) {
// some operation with number phone
Intent intentService = new Intent(context, ServiceMain.class);
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
context.startForegroundService(intentService);
}else {
context.startService(intentService);
}
}
}
}
}
}
MyReceiverSms.class
public class MyReceiverSms extends BroadcastReceiver {
private static final String TAG="MyReceiverSms";
private static final String ACTION="android.provider.Telephony.SMS_RECEIVED";
#Override
public void onReceive(Context context, Intent intent) {
Log.i("123","sakuraso13 ReceiverWorking");
if(intent != null && intent.getAction()!=null) {
if (intent.getAction().equals(ACTION)) {
// some operation with number phone
Intent intentService=new Intent(context, ServiceMain.class);
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
context.startForegroundService(intentService);
}else {
context.startService(intentService);
}
}
}
}
}
}
ServiceMain.class
public class ServiceMain extends Service {
public ServiceMain() {

Sometimes in logs I can see similar when calling when the application is closed:

I'm trying to add in-app purchases and when I call OpenIabHelper::launchPurchaseFlow function:
I see Google Play purchase window
onStop and onDestroy are executed in my main activity without calls to onActivityResult
So in the end I left with GooglePlay window and my dead app
I tried to start another activity via startActivityForResult and it worked fine
(nothing was destroyed and onActivityResult was called), so it seems that problem is with OpenIAB library
Therefore there's my question:
What can possibly force my activity to be destroyed after calling OpenIabHelper::launchPurchaseFlow ?
It doesn't seem to be system because it has enough memory and as I said startActivityForResult works fine.
Also there's no exceptions being trown so I'm puzzled
Any help would be appreciated
MyActivity.java
public class MyActivity extends AppCompatActivity {
private OpenIabHelper m_helper;
private Boolean m_bOpenIabInitialized = false;
#Override

super.onCreate(savedInstanceState);
OpenIabHelper.Options.Builder builder = new OpenIabHelper.Options.Builder()

m_helper = new OpenIabHelper(this, builder.build());
m_helper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
m_bOpenIabInitialized = result.isSuccess();
}
});
}
public void onListViewItemClicked(String sku, String payload) {
if (m_bOpenIabInitialized == null || !m_bOpenIabInitialized) return;
m_helper.launchPurchaseFlow(this, sku, 10001, null, payload);

Have you tried changing the activity's launchMode? Maybe the singleTop launch mode will preserve your activity:
<activity
android:name=".MyActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar"
android:configChanges="orientation|screenSize|keyboardHidden|screenLayout"
android:launchMode="singleTop">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
You can find more about launch modes here:

When I need to use Internet connection and it is not posible I want to set a broadcast receiver which keeps working if the app is closed.
I am using a service for that, but that it is not working. It works fine when the app is on screen or paused but it stops working if I close it. I am not pretty sure if I should use other thing or if I am doing something wrong.
This is my code:
package com.example.ana.exampleapp;
import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.content.SharedPreferences;
import android.os.IBinder;
import android.util.Log;
public class TestsService extends Service {
private static BroadcastReceiver networkChangeReceiver;
private static String TAG = "Service";
#Override
public IBinder onBind(Intent arg0) {
return null;
}
#Override
public void onCreate() {
Log.v(TAG, "Service created");
boolean keep = needTokeepWaiting()
if(!keep)
stopSelf();
}
#Override
public void onDestroy() {
if (networkChangeReceiver != null)
unregisterReceiver(networkChangeReceiver);
networkChangeReceiver = null;
Log.v(TAG, "Service destroyed");
}
private void registerNetworkChangeReceiver() {
networkChangeReceiver = new BroadcastReceiver() {
private String TAG = "NetworkReceiver";
#Override
public void onReceive(Context context, Intent intent) {
Log.v(TAG, "Connection changed received");
boolean keep = needTokeepWaiting()
if(!keep)
stopSelf();
}
};
IntentFilter filter = new IntentFilter(android.net.ConnectivityManager.CONNECTIVITY_ACTION);
registerReceiver(networkChangeReceiver, filter);
}
}
And my manisfest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.ana.exampleapp">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".MainActivity"
android:windowSoftInputMode="stateHidden">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".RegisterActivity"></activity>
<activity android:name=".FinishRegisterActivity"></activity>
<activity android:name=".TestActivity"></activity>
<activity android:name=".InformationActivity"></activity>
<service android:name=".TestsService"></service>
</application>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
</manifest>
And in the TestActivity when it is necessary I do:
Intent service = new Intent(this, TestsService.class);
startService(service);
What I am doing is similar to what it is suggested here, but it doesn't work:
Keep broadcast receiver running after application is closed
I have also tried to do it without a service and registering in the manifest, but It didn't work neither:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.ana.exampleapp">
<application
android:allowBackup="true"

android:supportsRtl="true"

android:windowSoftInputMode="stateHidden">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".RegisterActivity">
</activity>
<activity android:name=".FinishRegisterActivity" >
</activity>
<activity android:name=".TestActivity">
</activity>
<activity android:name=".InformationActivity" >
</activity>
<receiver android:name=".NetworkChangeReceiver"
android:enabled="false">
<intent-filter>
<action android:name="android.net.conn.CONNECTIVITY_CHANGE"/>
</intent-filter>
</receiver>
</application>
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
</manifest>
I have just found the problem. There is a bug in Android 4.4.x which kills background services when closing the app. I was testing my app in Android 4.4.2. Here there is a detailed explanation:
http://www.androidpolice.com/2014/03/07/bug-watch-stopping-apps-on-android-4-4-2-can-silently-kill-related-background-services-a-fix-is-on-the-way/
So my code was right as I have tried in Android 4.2.2 and it works (I have tried overriding onStartCommand() so maybe that was needed).
If you don't want your service to stop when the app is closed, you should override onStartCommand() method doing something like this:
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
return START_REDELIVER_INTENT;
}
You can return START_STICKY or START_REDELIVER_INTENT, whatever works better for you
I am wanting to start a service (CheckTime) when the phone finishes booting. This appears to work, but my app immediately crashes. I get the following error "java.lang.RuntimeException: Unable to start receiver com.example.alarmtest.MyReceiver: java.lang.UnsupportedOperationException: Not yet implemented". I have been unsuccessful in my attempts to solve this problem. I am unsure if I have left something out of the manifest or not (I am fairly new to developing for android).
This is my code for MyReceiver. (the log.d for this appears)
public class MyReceiver extends BroadcastReceiver {
public MyReceiver() {
}
#Override
public void onReceive(Context context, Intent intent) {
Intent startServiceIntent = new Intent(context, CheckTime.class);
context.startService(startServiceIntent);
Log.d("evan alarm", "Started on Launch, android autostart");
throw new UnsupportedOperationException("Not yet implemented");
}
}
and the code for CheckTime (the log.d for this never appears)
public class CheckTime {
public void loglab(){
Log.d("evan alarm", "We are now in CheckTime");
}
}
and finally the manifest.

That's the last line of your receiver. You're throwing it yourself.
remove this line
throw new UnsupportedOperationException("Not yet implemented");
I use my Main Activity to paint Text. Now Ive a Service in Background that listens to a bluetooth device. If a button on the device is pressed I insert values in the local database and want to repaint the correct value in my Main Activity. Everything works fine - just the repaint does not work, because i cant call the invalidate() method from my Service.
I tried with a BroadCastReceiver but i think i misunderstood something.
This is my Method in my Service "ControllerService"
private void insertToDB(int iWert, char c) {
if(zt.getJoystickMoved().x == iWert) {
sendOrderedBroadcast(i,null);
Log.i("Broadcast","send!");
//in this block i want to notify the Activity
}
}
Here is my Main Activity
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
registerReceiver(resetReceiver, new IntentFilter("my.intent.INTENT_NAME"));
}
public BroadcastReceiver resetReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
Log.i("Broadcast", "got Broadcast!");
MainActivity.this.cc.invalidate();
//cc.invalidate() repaints my Activity
//cc is a View with the paint Logic inside
this.setResultCode(Activity.RESULT_OK);
}
}
My Broadcast Receiver in my Main Activity does not receive anything ...
I hope someone could help me with my Problem.
