android 8.0 appwidget跳转apk进程失败

1.appwidget中没有界面，点击直接跳转到app无法启动

2.解决方法

1）新建一个EmptyActivity，activity中的finish界面

public class EmptyActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        finish();
    }
}

2）在跳转app之前，先跳转到这个空置的界面

//跳转空的activity
try {
   Intent emptyIntent = new Intent(context, EmptyActivity.class);
   emptyIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
   context.startActivity(emptyIntent);
} catch (Exception e) {
   Log.e(TAG, "EmptyActivity Intent e = " + e.toString());
}

//跳转app

Intent mapIntent = new Intent();
mapIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
ComponentName componetName = new ComponentName( "xxx","xxxxActivity");
mapIntent.setComponent(componetName);
context.startActivity(mapIntent);

3.成功跳转
