实际开发过程中Bug的处理-上报bug
程序异常终止的处理，强行停止，程序崩溃处理，UncaughtExceptionHandler
| bug处理流程： 1、在有bug的程序中，重写未捕获异常的默认handler Thread.setDefaultUncaughtExceptionHandler(new MyUncaughtExceptionHandler()); 2、实现该handler，将错误给保存下来，或者上传到服务器上 3、然后该handler自己杀死自己 Process.killProcess(Process.myPid()); |
| 1、有bug的程序 public class MainActivity extends Activity {
String s;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Thread.setDefaultUncaughtExceptionHandler(new MyUncaughtExceptionHandler());
s.equals("11");
}
}
|
| 2、重写未捕获异常的默认处理器 MyUncaughtExceptionHandler.java package cn.zengfansheng.bugreport;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.io.PrintStream;
import java.lang.Thread.UncaughtExceptionHandler;
import android.os.Environment;
import android.os.Process;
public class MyUncaughtExceptionHandler implements UncaughtExceptionHandler {
@Override
public void uncaughtException(Thread thread, Throwable ex) {
System.out.println("发生了未捕获的异常,但是被哥被捕获了...");
try {
// 1、StringWriter
// StringWriter sWriter = new StringWriter();
// PrintWriter err = new PrintWriter(sWriter);
// ex.printStackTrace(err);
//
// File file = new File(Environment.getExternalStorageDirectory(), "error.log");
// FileOutputStream fos = new FileOutputStream(file);
// fos.write(sWriter.toString().getBytes());
// fos.close();
// 2、
File file = new File(Environment.getExternalStorageDirectory(), "error1.log");
OutputStream out = new FileOutputStream(file );
PrintStream err = new PrintStream(out );
ex.printStackTrace(err );
out.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
// 自己杀死自己，自杀 早点重新投胎
Process.killProcess(Process.myPid());
}
}
