some apps will hang and fail to decrypt. only workaround for this is to launch them before u run the script.

[Amachik]

if u launch them before, it will use else and that way it will work.
if u dont launch the app before the decryption, it will use if not pid which will fail to work.
u can test this with app called HeadBall 2. but this app is just one of many.

def open_target_app(device, name_or_bundleid):
    print('Start the target app {}'.format(name_or_bundleid))

    pid = ''
    session = None
    display_name = ''
    bundle_identifier = ''
    for application in get_applications(device):
        print("for application")
        if name_or_bundleid == application.identifier or name_or_bundleid == application.name:
            print("if name_or_bundleid")
            pid = application.pid
            display_name = application.name
            bundle_identifier = application.identifier

    try:
        if not pid:
            print("if not pid")
            pid = device.spawn([bundle_identifier])
            session = device.attach(pid)
            device.resume(pid)
        else:
            print("else")
            session = device.attach(pid)
    except Exception as e:
        print(e)

    return session, display_name, bundle_identifier
