其他app引用

  • AndroidManifest加权限
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
  • AndroidManifest设置application的值
<application android:allowBackup="true" 
      android:icon="@drawable/ic_launcher" 
      android:label="@string/app_name" 
      android:name=".CrashApplication">
  • 需要在自己的application引用
import android.app.Application;
import com.shikun.crashhandler.*;  #引用打包的jar
public class CrashApplication extends Application  {
    @Override  
    public void onCreate() { 
     super.onCreate();  
     CrashHandler mCrashHandler = CrashHandler.getInstance();  
     mCrashHandler.setCustomCrashHanler(getApplicationContext()); 
    }
}

日志分析

  • 自己随便制造一个闪退运行程序，你会发现一句很友好的“很抱歉，程序遭遇异常，即将退出”代替了冷冰冰的警告框
  • 我们打开DDMS，在mnt/sdcard/Crash/目录下面发现了有一个文件，打开文件，我们可以看到
versionCode = 1  
PRODUCT = sdk  
MODEL = sdk  
versionName = 1.0  
SDK_INT = 8
