Android 判斷app是否在前台還是在背景運作
Android 判斷app是否在前台還是在背景運作，直接看代碼，可直接使用。
public static boolean isBackground(Context context) {
ActivityManager activityManager = (ActivityManager) context
.getSystemService(Context.ACTIVITY_SERVICE);
List appProcesses = activityManager
.getRunningAppProcesses();
for (RunningAppProcessInfo appProcess : appProcesses) {
if (appProcess.processName.equals(context.getPackageName())) {
Log.i(context.getPackageName(), "此appimportace ="
+ appProcess.importance
+ ",context.getClass().getName()="
+ context.getClass().getName());
if (appProcess.importance != RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {
Log.i(context.getPackageName(), "處于背景"
+ appProcess.processName);
return true;
} else {
Log.i(context.getPackageName(), "處于前台"
+ appProcess.processName);
return false;
}
}
}
return false;
}
