Android异常捕获记录本地

声明与初始化SP,自定义异常捕获
继承UncaughtExceptionHandler重写uncaughtException
在里面进行写入文件的操作,每条异常前最好使用分割线和日期作为分隔
可以等待3秒左右直接强退应用
然后再Application里注册

public class BaseException extends RuntimeException {
private static final long serialVersionUID = 8013687806066914955L;

public BaseException() {
super();
}

public BaseException(String detailMessage, Throwable throwable) {
super(detailMessage, throwable);
}

public BaseException(String detailMessage) {
super(detailMessage);
}

public BaseException(Throwable throwable) {
super(throwable);
}

}

public abstract class BaseCrashHandler implements UncaughtExceptionHandler{

@Override
public void uncaughtException(Thread thread, Throwable ex) {

if (handleException(ex)) {
try {
Thread.sleep(3000);
} catch (Exception e) {
e.printStackTrace();
}
System.exit(1);
}
}
public abstract boolean handleException(Throwable ex);
}

public class CrashHandler extends BaseCrashHandler {
private Context context;

public CrashHandler(Context context) {
this.context = context;
}

@Override
public boolean handleException(Throwable ex) {
if (ex == null) {
return false;
}

new Thread() {

@Override
public void run() {
Looper.prepare();
Toast.makeText(context, "程序异常退出啦撸!!!", Toast.LENGTH_SHORT).show();
Looper.loop();

}.start();

saveLog(ex);

OutputStream out = new FileOutputStream(errorFile, true);
out.write(("\n\n-----错误分割线" + DateFormat.format("yyyy年MM月dd日 HH时mm分ss秒 E ", new Date()) + "-----\n\n").getBytes());
