android-emulator

问题 I'm completely new to Android and Android Studio. I was just coding. So I was running the previous version of Android Emulator and it worked perfectly fine. However, when I downloaded the latest Android Emulator 27.1.12, my Emulator couldn't run properly. Issue: The code is running fine, but the Emulator can't display my application. When I click on the Emulator screen, I can still hear the Audio of my app. So I think the problem would be with my computer's hardware. Because the Emulator

问题 In the code I try to read from a web service with an http client. Then I want to write the Responce Phrase of the http responce to a text view. The UI is accessed through onPostExecute() so I don't know why I get this exception.

问题 I'm trying to develop a small app that will be registered on PhoneStateListener and do some magic over incoming and outgoing calls monitor. For debugging purposes, I need to trigger onCallStateChanged(...) event from outside of phone, not perform real incoming voice call. Is it possible to do this somehow with sending phone number to debugged app without command line code? 回答1: create one more emulator on avd machine.

问题 In emulator db file is located inside the /data/data/com.example.app_name/databases/data.db. But in real device no such directory exists. Due to which application crashes.

Also, when I displayed the directory for application through this.getDatabasePath() inside the device via toast it displays //data/data/com.example.My_App but as soon as database

Then save the actions in database. What I need is a service that fires when a calendar event occurs so I can catch the event id and compare it with actions in my database and do the actions that the

问题 When I launch an Android app via Ctrl+F11 on Eclipse, there are two black command windows (DOS-like) that appear briefly with some important messages in them. Obviously, I can't read what's in them in that brief moment. Is there a way to pause/freeze them? Update: @Mayra's answers below provided great tips but they did not solve the problem of pausing/freezing these windows. I know for sure that they contain information not in the Console and not in the logcat. So the question remains. 回答1: I

问题 I've read a bunch of articles on SO and around the web that all tell me that the android emulator connects to my machine with the ip address 10.0.2.2 when using localhost . Unfortunately I'm not using localhost , I've edited my hosts file so that I connect to local.blah.com when I want to view my webpage. I thought that if I write: 10.0.2.2 local.blah.com in my host file it would allow my to see the webpage I am developing in the android emulator. (Please correct me if this was not a good
