每次我从应用模块调用库模块上的活动时，应用都会崩溃

应用模块上有一个按钮，当它被按下时，它将调用库模块中的活动，但是每次我这样做，应用都会崩溃

下面是应用模块上的代码，意图将在其中调用库模块上的主要活动

这是应用模块上的android清单

 //Audio Activity
    audioButton = (ImageView) findViewById(R.id.IV_main_audio);
    audioButton.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View v){
            Intent intentLoadNewActivity = new 
    Intent("com.danielkim.soundrecorder.MainActivity");
            startActivity(intentLoadNewActivity);
        }

    });

Answer 1

糟糕的是，反射可以用来从libary模块启动您的Activity：

Class.forName（“ com.mypackage.MainActivity”）

try {
    Intent myIntent = new 
    Intent(this,Class.forName("com.danielkim.soundrecorder.MainActivity"));
    startActivity(myIntent);

    } catch (ClassNotFoundException e) {
     e.printStackTrace();
  }

Answer 2

Intent i=new Intent(PresentActivity.this, NextActivity.class);
startActivity(i);

Answer 3

audioButton = (ImageView) findViewById(R.id.IV_main_audio);
audioButton.setOnClickListener(new View.OnClickListener(){
    @Override
    public void onClick(View v){
        try{
            // try another constructor
            Intent intentLoadNewActivity = new Intent(v.getContext(), "com.danielkim.soundrecorder.MainActivity");
            // add optional flag FLAG_ACTIVITY_NEW_TASK if necessary.
            // intentLoadNewActivity.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(intentLoadNewActivity);
        } catch (Exception e) {
             Log.e("TAG",e);// if still not work, please show us the log.
        }
    }
});

Answer 4

（代表问题作者发布的解决方案）。

经过一些搜索，我已经解决了。我只是在app模块和库模块上有一个重复的文件名。
