我用廣播接收器開始我就啓動應用程序,但它沒有啓動應用程序沒有啓動的設備引導
這裏是我的代碼
清單代碼:
<?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" >

廣播級代碼:
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類別:
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();
}
});
}
}

當MainActivity不是'Service'時,爲什麼使用'startService()'?你需要使用'startActivity()'來代替。 – m0skit0
