问题描述
ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);ComponentName cn = am.getRunningTasks(1).get(0).topActivity;
这种方法在Android 5.0以上就不能用了,返回的都是桌面包。5.0以后如何判断?还望大神赐教!
问题解答
回答1:你这是在做launcher吗?检测某Activity是否在当前Task的栈顶
回答2:你可以尝试下面的方法:
ActivityManager mActivityManager =(ActivityManager)this.getSystemService(Context.ACTIVITY_SERVICE);if(Build.VERSION.SDK_INT > 20){ String mPackageName = mActivityManager.getRunningAppProcesses().get(0).processName;}else{ String mpackageName = mActivityManager.getRunningTasks(1).get(0).topActivity.getPackageName();}
