问题 Background For a very long time, there wasn't an official API for blocking calls on Android. What developers did for CallerId and call-blocking apps, is to use some reflection tricks, as shown here. The problem It seems no blocking app works on Android P DP3 (tested on Pixel 2). Even very popular apps such as TrueCaller fail to block calls. I believe this is because it might be replaced with an official API, as there are some articles that talk about built in call blocking capability for

问题 I am developing a wifi search application. Whenever the device is in aeroplane mode wifi is turned off automatically. I found that system apps can turn on the wifi even if the device is in aeroplane mode. I am testing it on Android 9.

On logcat, I see a warning "Warning 889 InputMethodManagerService Ignoring showInputMethodPickerFromClient of uid

问题 So we can get for example safe inset top value (useful for devices which have notch/cutout): override fun onAttachedToWindow() { super.onAttachedToWindow() if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) { val safeInsetTop = window.decorView.rootWindowInsets?.displayCutout?.safeInsetTop if (DEBUG) Timber.d("onAttachedToWindow, safeInsetTop: $safeInsetTop") } } override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) if (DEBUG) Timber.d("onCreate") if

问题 I try to open PDF file in Pie? but it does not open. I don't get any error. What is the issue? PDF file does not open. Only black screen is shown. In logcat no errors show. What is wrong? Intent intent = new Intent(Intent.ACTION_VIEW); Uri outputFileUri; if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { outputFileUri = FileProvider.getUriForFile(this, BuildConfig.APPLICATION_ID + ".provider", file); } else outputFileUri = Uri.fromFile(file); Log.e("TAG", "outputFileUri-> " + outputFileUri
