android 自己採集crash信息

引起crash

public class MainActivity extends Activity {

	Button click2Crash;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Log.i("Thread0", Thread.currentThread()+"");
        Thread.setDefaultUncaughtExceptionHandler(new UncaughtExceptionHandler(this));

        
        click2Crash = (Button)findViewById(R.id.clickToCrash);
        
        click2Crash.setOnClickListener(new Button.OnClickListener(){
			@Override
			public void onClick(View v) {
//				String text = "aaa";
//				System.out.print(text.charAt(10));
				TextView t = null;
				t.setText("abc");
			}});
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
}

自動捕捉stackTrace

public class UncaughtExceptionHandler implements
java.lang.Thread.UncaughtExceptionHandler {
	private Context con_;
	public UncaughtExceptionHandler(Context con){
		this.con_ = con;
	}
	@Override
	public void uncaughtException(Thread thread, Throwable ex) {
		StringWriter sw = new StringWriter();
		ex.printStackTrace(new PrintWriter(sw));
		System.err.println(sw);
		Intent bugReportIntent = new Intent(con_, BugReportActivity.class);
		bugReportIntent.putExtra(BugReportActivity.exceptionMsg, sw.toString());
		con_.startActivity(bugReportIntent);

		android.os.Process.killProcess(android.os.Process.myPid());
		System.exit(10);// this is very important, we can got next activity
	}
}

跳到一個新的activity

public class BugReportActivity extends Activity {
	public static final String exceptionMsg = "exceptionMsg";
	
	private TextView reportContent;
	private Button sendMailBtn;
	private Button cancelBtn;
	
	protected void onCreate(Bundle bundle){
		super.onCreate(bundle);
		Thread.setDefaultUncaughtExceptionHandler(new UncaughtExceptionHandler(this));
//		ACRA.init(getApplication());
//		ACRA.getErrorReporter().putCustomData("formKey", "");
//		ACRA.getErrorReporter().putCustomData("formKey", "");
//		
		setContentView(R.layout.bug_report);
		
		reportContent = (TextView)findViewById(R.id.reportContent);
		sendMailBtn = (Button)findViewById(R.id.sendMail);
		cancelBtn = (Button)findViewById(R.id.cancel);
		
		String sw = getIntent().getStringExtra(exceptionMsg);
		reportContent.setText(sw);
		
		initHandler();
	}
	
	private void initHandler(){
		sendMailBtn.setOnClickListener(new Button.OnClickListener(){
			@Override
			public void onClick(View v) {
				Toast.makeText(v.getContext(), "Email will be sent to our helpdesk.", Toast.LENGTH_LONG).show();
				
			}
		});
		cancelBtn.setOnClickListener(new Button.OnClickListener(){
			@Override
			public void onClick(View v) {
				finish();
			}
		});
	}
}
