Changing the Vibrate settings in Jelly Bean, Android

由 烂漫一生 提交于 2019-12-04 17:18:59
I am looking for how we change the vibrate settings in Jelly Bean. I found that all the pre-JB vibrate settings have been deprecated, but don't see any new AudioManager.[change the vibrate settings] code anywhere. There is a setting "Vibrate when ringing" which I would like to know how to play with. Thanks for you help. house In android4.1 you can use this to control "vibrate & ringing" Settings.System.putInt(mContentResolver, Settings.System.VIBRATE_WHEN_RINGING, enable ? 1 : 0); From the Documentation: This method is deprecated. Applications should maintain their own vibrate policy based on

Hiding the Status Bar under Android 4.2.2 (SDK 17)

Is it possible to permanently hide Navigation/Status Bar under Android 4.2.2 This solution seems not working under Jelly Bean. I have GalaxyTab 3 (10.1) and hidding of Status Bar has no effect. It's hidden on application Start on every screens, but i can expand it. Problem occurs also after rooting device. Somebody has faced it before (there is also video how to fix it): forum.xda-developers.com/showthread.php?p=37466852 So my question is: Is there any way to do this on application level? No, it seems like there is no way to do this for your entire application on tablets running 4.+. Also,

Android 4.2 with 4 MediaPlayers = “Can't play this video”

由 我与影子孤独终老i 提交于 2019-12-04 01:07:39
问题 Whenever I'm trying to load at least 4 mediaPlayers, one of them will corrupt the video it's trying to load and trigger an Android OS message "Can't play this video" Other information: For 3 mediaPlayers everything works fine. On other Android versions, different from 4.2, the same code with the same 4 video works. The 4 video can be played independently on the device. There is no format problem. After starting the program and getting the "Can't play this video" message, the video can no

onEditorAction() is not called after Enter key has been pressed on Jelly Bean emulator

由 南楼画角 提交于 2019-12-03 14:55:10
问题 I'm having a problem with the behavior of the latest Jelly Bean emulator. I have several EditTexts in my app. An OnEditorActionListener provides special handling when a user presses the ENTER key on the keyboard. This worked up until ICS, but now on Jelly Bean the listener callback method onEditorAction() no longer gets called. Only a new line is inserted into the EditText . This can be reproduced this way: EditText testEditText = new EditText(context); testEditText.setOnEditorActionListener

WiFi-Direct on JellyBean, WPA Supplicant messed up

由 青春壹個敷衍的年華 提交于 2019-12-03 13:42:48
问题 so a couple of months ago I've started developing some WiFi-Direct applications. A few days ago, I updated both of my Galaxy Nexus to Jelly Bean (4.1.x) and tested my applications, but it seems like there's something messed up again.. It was already a pain in the ass to get the main functionality set up on ICS, but now it does not work anymore. All i get is something like this in my logcat: /wpa_supplicant( 392): p2p0: P2P-PROV-DISC-PBC-REQ a2:0b:ba:xy:zz:xx p2p_dev_addr=a2:0b:ba:xy:zz:xx pri
