Android 收集奔溃信息

1.  ExceptionCrashHandler implements Thread.UncaughtExceptionHandler 继承 

 //  当App 奔溃的时候回调用这个方法
@Override
public void uncaughtException(Thread thread, Throwable ex) {
Log.e(TAG, "到拦截闪退信息");
    //  手机信息+应用信息+  捕获异常写入  sd 卡
// 捕获到异常了，写入到本地，让系统默认处理
String crashFileName = saveInfoToSD(ex);

        Log.e(TAG, "fileName --> " + crashFileName);

        //  缓存崩溃日志文件, 下次启动App把奔溃信息上次到服务器
cacheCrashFile(crashFileName);
// 系统默认处理
// mDefaultHandler.uncaughtException(thread, ex);

  // 让系统默认处理
// 奔溃，关闭当前activity返回上一个activity
mDefaultHandler.uncaughtException(thread,ex);
}

2.  MyApplication初始化 ExceptionCrashHandler 

public class MyApplication extends Application {public static PatchManager patchManager;@Overridepublic void onCreate() {super.onCreate();// 设置全异常捕捉类ExceptionCrashHandler.getInstance().init(this);}
}

3、 App再次启动，读取奔溃信息上次到服务器中

public class MainActivity extends Activity {private final int SDK_PERMISSION_REQUEST = 127;String Tag= "denganzhi";@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);ArrayList<String> permissions = new ArrayList<String>();if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {// 定位精确位置if(checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED){permissions.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);}// 用户点击拒绝，每一次申请都会回调if (permissions.size() > 0) {requestPermissions(permissions.toArray(new String[permissions.size()]), SDK_PERMISSION_REQUEST);}}// 获取异常上次奔溃信息File crashFile = ExceptionCrashHandler.getInstance().getCrashFile();if(crashFile.exists()){//文件存在上传服务器String resultText = readToString(crashFile.getAbsolutePath());Log.e("denganzhi1","奔溃信息是:"+resultText);}}// 读取奔溃信息public String readToString(String fileName) {String encoding = "UTF-8";File file = new File(fileName);Long filelength = file.length();byte[] filecontent = new byte[filelength.intValue()];try {FileInputStream in = new FileInputStream(file);in.read(filecontent);in.close();} catch (FileNotFoundException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}try {return new String(filecontent, encoding);} catch (UnsupportedEncodingException e) {System.err.println("The OS does not support " + encoding);e.printStackTrace();return null;}}@TargetApi(23)@Overridepublic void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {// TODO Auto-generated method stubif (requestCode == SDK_PERMISSION_REQUEST){if (grantResults[0] == PackageManager.PERMISSION_GRANTED  ){//  callPhone();Toast.makeText(MainActivity.this,"权限通过："+grantResults.length,Toast.LENGTH_SHORT).show();}else {Toast.makeText(MainActivity.this,"用户点击拒绝："+grantResults.length,Toast.LENGTH_SHORT).show();}return;}super.onRequestPermissionsResult(requestCode, permissions, grantResults);}}
