CrashHandler捕获全局异常

public class CrashHandler implements UncaughtExceptionHandler {
public static final String TAG = "CrashHandler";
private static CrashHandler INSTANCE = new CrashHandler();
private UncaughtExceptionHandler mDefaultHandler;
private CrashHandler() {
}

public static CrashHandler getInstance() {
return INSTANCE;
}

public void init(Context context) {
mDefaultHandler = Thread.getDefaultUncaughtExceptionHandler();
Thread.setDefaultUncaughtExceptionHandler(this);
}

/**
* 当UncaughtException发生时会转入该函数来处理
*/
@Override
public void uncaughtException(Thread thread, Throwable exception) {
final Writer result = new StringWriter();
final PrintWriter printWriter = new PrintWriter(result);
exception.printStackTrace(printWriter);
LogUtil.log("app uncaughtException:" + result.toString());
printWriter.close();
mDefaultHandler.uncaughtException(thread, exception);
}

}

使用可以在继承的application类中onCreat：CrashHandler crashHandler = CrashHandler.getInstance();crashHandler.init(getApplicationContext());

这样可以将抛出的异常存入在文件中。
