[英]Application is not starting on device boot
I used BroadcastReceiver to start my application on boot, but it is not starting 我使用BroadcastReceiver在启动时启动我的应用程序,但它没有启动
here is my code 这是我的代码
Manifest code : 清单代码:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.copy"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="9" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<receiver android:name="com.copy.MyBroadcastreceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<activity
android:name="com.copy.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Broadcast class code: 广播类代码:
public class MyBroadcastreceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
Intent startServiceIntent = new Intent(context, MainActivity.class);
startServiceIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startService(startServiceIntent);
}
}
MainActivity class : MainActivity类:
public class MainActivity extends Activity
{
ListView lView;
private ArrayList results = new ArrayList();
@SuppressWarnings("unchecked")
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lView = (ListView) findViewById(R.id.list1);
PackageManager pm = this.getPackageManager();
Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
List<ResolveInfo> list = pm.queryIntentActivities(intent,PackageManager.PERMISSION_GRANTED);
for (ResolveInfo rInfo : list)
{
results.add(rInfo.activityInfo.applicationInfo.loadLabel(pm).toString());
Log.w("Installed Applications", rInfo.activityInfo.applicationInfo.loadLabel(pm).toString());
}
lView.setAdapter(new ArrayAdapter(this,android.R.layout.simple_list_item_1, results));
lView.setOnItemClickListener(new OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3)
{
String x = (String) arg0.getItemAtPosition(arg2);
Toast.makeText(getApplicationContext(), "This is "+lView.getItemAtPosition(arg2), Toast.LENGTH_SHORT).show();
}
});
}
}
You are using startService()
and MainActivity
is not a Service
. 您正在使用
startService()
而MainActivity
不是Service
。 You need to use startActivity()
instead. 您需要使用
startActivity()
。
public class MyBroadcastreceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
Intent startActivityIntent = new Intent(context, MainActivity.class);
startActivityIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(startActivityIntent);
}
}
Try starting an Activity as opposed to Service:- 尝试启动活动而不是服务: -
Intent i = new Intent(context, MainActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
Yes, call startActivity : 是的,调用startActivity :
@Override
public void onReceive(Context context, Intent intent) {
Intent startActivityIntent = new Intent(context, MainActivity.class);
startActivityIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(startActivityIntent);
}
