android-emulator

问题 The issue I have, is that i can't extract the file exetension from files choosen on a smartphone with Android 9. The problem doesn't appear on devices with Android 8 or less. When the user has choosen any kind of file the onActivityResult gets called. In this method I call getPath from FileUtils class, so I can extract the file extension. @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { Uri uri = new Uri.Builder().build(); if (resultCode == RESULT_OK)

问题 I want to hide the edit text and button field initially in list view and show that edit text and button for a particular raw in list view when that raw is clicked.So I tried to set the height to 0 in layout xml and then set it to some other value when user clicks on a raw, but it is not working I think my list view click event is not working. In the Android layout that I have list view there are Image view as a button, edit text field and list view also. Like follows <RelativeLayout xmlns

问题 "emulator: warning: opening audio input failed" The above message is displayed in the console everytime an AVD is launching , and then no sound is coming out from the emulator. I have tried to delete the AVD and have created a new one again and again, but it didn't help with the problem. I have also searched on Google for many time, but I find nothing useful. It is really interesting that people tend to suggest to just ignore the problem because the AVD is still working fine without sound.

问题 I am trying to test an Android application. I need to send mock location to test this. I have registered for requestlocation updates(..)method (as follows) locationManager.requestLocationUpdates(bestProvider, 20000, 0, this); Tried sending mock locations through Eclipse DDMS tab as well as telnet-ing from command prompt. telnet commands as follows telnet localhost 5554 geo fix 1 1 The application works fine (i.e. receives the location changed event) if I run using AVD Emulator using 1.6 to 2
