好吧，这是一个自动启动应用程序的完整示例
AndroidManifest文件
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="pack.saltriver" android:versionCode="1" android:versionName="1.0"> <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /> <application android:icon="@drawable/icon" android:label="@string/app_name"> <receiver android:name=".autostart"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> </intent-filter> </receiver> <activity android:name=".hello"></activity> <service android:enabled="true" android:name=".service" /> </application></manifest>
自动启动
public class autostart extends BroadcastReceiver { public void onReceive(Context context, Intent arg1) { Intent intent = new Intent(context,service.class); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) { context.startForegroundService(intent); } else { context.startService(intent); } Log.i("Autostart", "started"); }}service.javapublic class service extends Service{ private static final String TAG = "MyService"; @Override public IBinder onBind(Intent intent) { return null; } public void onDestroy() { Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show(); Log.d(TAG, "onDestroy"); } @Override public void onStart(Intent intent, int startid) { Intent intents = new Intent(getbaseContext(),hello.class); intents.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intents); Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show(); Log.d(TAG, "onStart"); }}hello.java-执行一次Applicaton后，每次启动设备时都会弹出此窗口。
public class hello extends Activity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Toast.makeText(getbaseContext(), "Hello........", Toast.LENGTH_LONG).show(); }}
