问题 My Logcat output for my program failing. It apparently can't access some kind of SD card, but I'm using the emulator. I'm on x64 windows 7, and I ran as administrator. 08-29 19:16:29.360: ERROR/AndroidRuntime(707): FATAL EXCEPTION: GLThread 10 08-29 19:16:29.360: ERROR/AndroidRuntime(707): java.lang.ExceptionInInitializerError 08-29 19:16:29.360: ERROR/AndroidRuntime(707): at com.wickeyware.zombiearcher.screen.TitleScreen.render(TitleScreen.java:80) 08-29 19:16:29.360: ERROR/AndroidRuntime

问题 I have several Android projects in an Eclipse workspace: a stand-alone application project with a class my.package.Foo a library project with a different class my.package.Foo two application projects that depend on the library project and contain no source code The problem comes when working with one of the applications built on top of the library project. When it crashes (sadly, a frequent occurrence), I double-click on a line of the stack trace in the logcat to go to the relevant source.

问题 In LogCat, when I click the "clear all" button, it appears to clear all of the logs. However, if I change the log level, and come back to the previous log level, all of the logs have returned. For example, I'm looking at "Verbose". I choose "Clear all". The log clears. I switch over to "Debug". I switch back to "Verbose", now all of the Verbose logs that I thought I cleared, have now come back. It displays everything since I opened Android Studio. Additionally, the same issue occurs if I

问题 I have a HashMap<String, LinkedHashMap<String,String> that is fairly long (not an issue) and I'm trying to make sure things look correct before I use the data inside it. To do this I'm trying to just attempting to do this Log.v("productsFromDB",products.toString()) but in the LogCat It shows about 1/3 of it. Is there a way to output the entire map? 回答1: Logcat can only show about 4000 characters. So you need to call a recursive function to see the entire hashmap. Try this function: public

问题 The problem I am having is that the onCreate() method within my MainActivity cannot seem to start another activity. I have code working so that when I click a button, my "AboutActivity" is started. However, I want to make it so that "AboutActivity" is started as soon as onCreate() in the MainActivity finishes. The program gets caught up at a blank screen when I run it while trying to start the "AboutActivity" from onCreate(). The code posted is a simplified version of the problem. In essence,

问题 I am trying to record audio clips with MediaRecorder, but I keep getting these errors in my Logcat when I start, stop, and start again; the activity would also close: INFO/DEBUG(1285): *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** INFO/DEBUG(1285): Build fingerprint: 'LGE/thunderg/thunderg/thunderg:2.2.1/FRG83/eng.nikech.choi.20110126.134422:user/release-keys' INFO/DEBUG(1285): signal 11 (SIGSEGV), fault addr 00000010 INFO/DEBUG(1285): r0 00000000 r1 00000000 r2 a930cc98 r3

问题 I have an application and I'd like to collect the LogCat messages of a specified level and tag. Can I somehow get the accumulated messages at some point? I don't want to collect the messages one by one, it should be the sum of them like when I use adb to read the actual log. Is this possible? 回答1: Try this: Note that in Android 4 you will only see the log messages that were written by your own app unless you have root access. public static String getLog(Context c) { try { Process process =
