Introduce a custom intent action to close software keyboard
This CL introduces a custom intent action for apps to ask AOSP Keyboard to close its software keyboard with guarding it with a signature-protected permission. Any app that is signed with the same signature as AOSP Keyboard can have the following line in AndroidManifest.xml <uses-permission android:name="com.android.inputmethod.latin.HIDE_SOFT_INPUT"/> to request AOSP Keyboard to close its software keyboard as follows. sendBroadcast(new Intent("com.android.inputmethod.latin.HIDE_SOFT_INPUT") .setPackage("com.android.inputmethod.latin")); Test: Manually verified with a test app. Fixes: 65270710 Change-Id: I4fd2e3a7336ec66c70582a2f274a200cbf035a7fmain
