我正在尝试获取当前打开的应用程序包名称,我得到了kitkat,但它将无法在android lollipop中运行,它每次都会返回我的安装应用程序包名称,我不知道为什么会发生这种情况,代码
private void getAppInfoLowerLolipop(Context aContext) {
ActivityManager am = (ActivityManager) aContext
.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningTaskInfo> alltasks = am.getRunningTasks(1);
for (ActivityManager.RunningTaskInfo aTask : alltasks) {
System.out.println("==== Not Package Name : "
+ aTask.topActivity.getPackageName().toString());
}
}
和Android棒棒糖和棉花糖
private void getAppInfoForLolipop(Context context) {
try {
ActivityManager.RunningAppProcessInfo.class
.getDeclaredField("processState");
ActivityManager am = (ActivityManager) context
.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> appList = am
.getRunningAppProcesses();
System.out.println("==== Lolipop Package Name : "
+ appList.get(0).processName.toString());
} catch (Exception ignored) {
System.out.println("==== Error Lolipop : " + ignored);
}
}
在清单文件中,我允许获取最近的任务
