problem:
No matter what I activity, when my phone switches to the main screen , or open , when other applications . Then return back to my app. How to get to this event ?
------ Solution ---------------------------------------- ----
let them inherit a unified class A Class A class which inherits ACtivity A on the realization of an operation of this onresume and onpause whether this can be solved it ?
Although onresume and onpause not a complete process, but no matter how you start the application how to exit the application must take this step .
------ Solution ---------------------------------------- ----
write a base class Activity
In onStop () determines the entire application is not in the phone reception. Then record flag flag
In onResume () where the decision is not based on flag gesture password. Reset flag flag
check whether an application running in the foreground code is as follows :
public boolean isAppOnForeground() {
// Returns a list of application processes that are running on the
// device
ActivityManager activityManager = (ActivityManager) getApplicationContext().getSystemService(Context.ACTIVITY_SERVICE);
String packageName = getApplicationContext().getPackageName();
List<RunningAppProcessInfo> appProcesses = activityManager.getRunningAppProcesses();
if (appProcesses == null)
return false;
for (RunningAppProcessInfo appProcess : appProcesses) {
// The name of the process that this object is associated with.
if (appProcess.processName.equals(packageName) && appProcess.importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {
return true;
}
}
return false;

onpause settings a flag bit , this is the activity Lane ?
Yes ah
activity of the pause to resume, not necessarily the entire application to be cut out ah. Moreover , you need to go for each activity in Canada, is not very troublesome thing ? This should think of ways to start it in the application

With you modify the internal startactivity when the first bit of the mark , you can avoid the internal switch when the lock screen . Other circumstances or in accordance with the above process to carry out his .

considering this logic Haha several conditions
I guess ah need two markers first marker bit indicates whether the application opens the lock
second marker bit indicates whether the need to open this lock

ActivityManager activityManager = (ActivityManager) getSystemService (ACTIVITY_SERVICE);
