Unlocking the emulator or device for Android test

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-12 16:15:56
问题 I am writing Android functional tests. I need the device to be awake and the application to be visualized in order for them to work. I have consulted with Android developers for that. However, there are several problems with the proposed solution: The proposed method now has several deprecated methods. Android API now advises me to use flags on the window: This class was deprecated in API level 13. Use FLAG_DISMISS_KEYGUARD and/or FLAG_SHOW_WHEN_LOCKED instead; this allows you to seamlessly

For api < 16: How to detect if PIN/password/pattern is required to unlock phone?

问题 I already know these two cases: 1) for devices using api >= 16, one could just use the method isDeviceSecure() from KeyguardManager and that would return true if any locking mechanism is used on the device (pattern, passcode, password, etc.) 2) for devices using api <= 15, one could do something like if (Settings.Secure.getInt(getContentResolver(), Settings.Secure.LOCK_PATTERN_ENABLED) == 0) , but that would only check for screen locking pattern (not passcode, password, etc.) So my question

Activity in front of Lockscreen

由 梦想的初衷 提交于 2019-12-08 02:20:07
问题 I want to create an activity in front of the lockscreen. I don't want to skip the keyguard completely. I tryed it with the TYPE_SYSTEM_OVERLAY flag but there I can't handel any events. It works with FLAG_SHOW_WHEN_LOCKED but then there is a black background and i want it like on this picture: An Activity without black background and event handling http://s1.directupload.net/images/130306/sctc586t.jpg It would be nice if it is like TYPE_SYSTEM_OVERLAY but with event handling. Is that possible?

问题 I'm working to implement a lock screen just like the water ripple lock screen of Samsung Galaxy 3. I have finished the GLSurfaceView object. But there is a problem when I port it to Lock Screen. The SurfaceView couldn't be displayed on Lock Screen whose window type is TYPE_KEYGUARD. If I use setZOrderOnTop(true) to this SurfaceView, it Can be displayed, but it will overlay all other layers of Lock Screen, which is not my anticipation. This SurfaceView can display normally on normal

With security keyguard active transition between activities is weird

由 穿精又带淫゛_ 提交于 2019-12-06 02:00:46
I have my main activity A and when the user presses a button i open another activity B. But when this happens B doesn't just appear on top of A: A disappears secure keyguard shows up B appears And when i get rid of B the same thing happens. This is annoying because there's a lot of flickering with no real purpose on the screen. Is there any way to achieve direct transition from A to B while keyguard is active without merging the 2 activities into 1? Here is what i'm doing in onCreate for both activities: getWindow().addFlags( WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD | WindowManager

由 末鹿安然 提交于 2019-12-05 01:05:41
问题 I want to control enabling/disabling keyguard on the device. To do that I'm using DevicePolicyManager and KeyguardLock API of Android SDK.
