Auto start an app when charging

Question

I am creating an Android application that I want to auto-start as soon as the mobile is plugged into charging or headphone is plugged into it. Please provide any solution as to how to do it.

Hey I prepare a demo for battery charging, just try it.

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.logistic.test1"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="8" />
    <uses-permission android:name="android.permission.BATTERY_STATS"/>
    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".Test1Activity"
            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 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>
        <class android:name=".PowerConnectionReceiver">
        </class>

</application>
</manifest>

PowerConnectionReceiver

package com.logistic.test1;

import android.content.BroadcastReceiver;
import android.content.Context;

import android.os.BatteryManager;
import android.widget.Toast;

public class PowerConnectionReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        boolean isCharging = false;
        int status = intent.getIntExtra(BatteryManager.EXTRA_STATUS, -1);
        if(status == 2)
            isCharging = true;
        //boolean isCharging = status == BatteryManager.BATTERY_PLUGGED_AC ||
            //  status == BatteryManager.BATTERY_PLUGGED_USB;
                //BATTERY_STATUS_CHARGING;
                //  || status == BatteryManager.BATTERY_STATUS_FULL;
        /*
         * int chargePlug = intent.getIntExtra(BatteryManager.EXTRA_PLUGGED,

         * BatteryManager.BATTERY_PLUGGED_AC;
         */
        Toast.makeText(context, "Status : "+status+"\nCharging : "+isCharging, Toast.LENGTH_SHORT).show();
    }

}

Test1Activity.java

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

    @Override
    public void onStart() {
        super.onStart();
        IntentFilter ifilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
        Intent batteryStatus = registerReceiver(null, ifilter);
        pcr = new PowerConnectionReceiver();
        pcr.onReceive(getApplicationContext(), batteryStatus);
    }

    @Override
    public void onStop() {

        try {

        } catch(IllegalStateException e) {
            e.printStackTrace();

    }

    @Override

    }

    private void showText(String msg) {

}

See my post for a better example. Yours didn't work from the start, sorry. — Aart den Braber, Mar 12 '14 at 14:23

To detect charging state, use BroadcastReceiver and register in your manifest file like ::

<receiver android:name=".broadcastReceiver">
  <intent-filter>
     <action android:name="android.intent.action.ACTION_POWER_CONNECTED"/>
     <action android:name="android.intent.action.ACTION_POWER_DISCONNECTED"/>
  </intent-filter>
</receiver>

and to detect headphone is plugged or not use AudioManager.isWiredHeadsetOn()

check this out

http://developer.android.com/training/monitoring-device-state/battery-monitoring.html

Receive

<receiver android:name=".broadcastReceiver">
  <intent-filter>
     <action android:name="android.intent.action.ACTION_POWER_CONNECTED"/>
     <action android:name="android.intent.action.ACTION_POWER_DISCONNECTED"/>
  </intent-filter>
</receiver>

Also receive

<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>

in your manifest

like this:

<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>

then:

public class PowerConnectionReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {

        IntentFilter ifilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
        Intent batteryStatus = context.registerReceiver(null, ifilter);


        int status = intent.getIntExtra(BatteryManager.EXTRA_STATUS, -1);
        boolean isCharging =    status == BatteryManager.BATTERY_STATUS_CHARGING ||
                                status == BatteryManager.BATTERY_STATUS_FULL;

        int chargePlug = intent.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);
        boolean usbCharge   = chargePlug == BatteryManager.BATTERY_PLUGGED_USB;
        boolean acCharge    = chargePlug == BatteryManager.BATTERY_PLUGGED_AC;


        if (batteryStatus != null) {
            int level = batteryStatus.getIntExtra(BatteryManager.EXTRA_LEVEL, -1);
            int scale = batteryStatus.getIntExtra(BatteryManager.EXTRA_SCALE, -1);
            float batteryPct = level / (float) scale;
        }


    }//end onReceive


}//end PowerConnectionReceiver

What if the batterypct is not in the range I want to start my activity? Let's say I want to start an activity only if it's charging AND battery level is above 90%, how to accomplish that? — Dpedrinha, May 08 '18 at 11:34
