Introduction and Example of Eventbus in Android.

EventBus is a library of Greenbot . This is very simple for all users how to implement and its basic use. Here I will also share examples for better understanding. What is EventBus? EventBus is subscribed/publish event bus to communication between components with limited lines of code, in short, its bus for events transfers the data between one activity(class) to another to reflect the changes based on our needs. That makes the data exchange between components like Activity, Fragment, Services, and any kind of backgrounds threads pretty easy. EventBus can handle the threading for us: events can be posted in threads different from the posting thread. Common use can be dealing with UI changes. In Android, UI changes must be done in the Main(UI) thread.

Disable Force Stop in Android


I have worked since 1 week on how to disable the FORCE STOP button in Manage Application in Android. And I was able to disable the Force Stop and Uninstall button in Manage Application.

For that you need to make your application as Device Administrator. Android has add this kind of feature from Android 2.2 version. This feature is for Security reason with different option. Set Minimum Password Strength, Data Wipe, Force Lock,  Reset Password and so on. We set our application as Device Administrator to change above features.

 For more info and advance example you can check your android-sdk path (>= android-8).  
 \samples\android-[>=8]\ApiDemos\src\com\example\android\apis\app\DeviceAdminSample.java

See the below screen shots which shows how to activate the application and disable force stop button.

      Thanks for your interest.

      I thought "Clear Cache" is not able to disable due to its System level button. But If I find anyhow then share it here.

      Thanks,

    Hi Prashant.

    I try to use your example in my Android, but this don´t disable the Force Stop button in settings.

    Only work the Uninstall button, when you try uninstaller. I had to add this line for uninstaller mDPM.removeActiveAdmin(mAdminName);

    Thanks for your answer.

      Hi Erick,

      Then it must be work in your device because its android > 2.2 version.

      You can check DeviceSample from below path in your Android-SDK path.

      Hi Pankaj,

      If you want to enable it again then go to Android device Settings -> Security -> Device Administrator -> and deselect the checkbox of your application.
      That's it.

    Hello Prashant:
    Nice code.

    Code runs ok in 4.4 but no in two Samsung with 2.3.6 (one GT P1000 and GT S6500). I tried "First installed old version and than try to install the fresh application again" but nothing. I have seen in several comments the same problem with 2.3.6... Buttons Force Close and Unistall are enabled although it is true uninstall finally no success. ¿A new advice to try?
