如何在Android中将主项目的意图数据发送到库项目？

Question

Intent myIntent = null;
    try {
        myIntent = new Intent(GetUserprofile.this,LockscreenActivity.class);

       myIntent.putExtra("examiddetails",exam_id);

        startActivity(myIntent);
    } catch (Exception e) {
        e.printStackTrace();
    }

Intent intent = getIntent();    
    try{
        if(intent != null){
            String Examid = intent.getStringExtra("examiddetails");
        }

    }catch(Exception e){
        System.out.println("getdataFromService exception"+e.toString());
    }

我正在获取库项目中Examid字符串的空值。

您的意思是将数据发送到另一个活动吗？我以前也做过。

MainProject类

Intent intent= new intent(getApplication(), LockscreenActivity.class);
intent.putExtra("examiddetails",exam_id);
startActivity(intent);

LockscreenActivity类

Bundle bundle = getIntent().getExtras();
String ExamIdDetails = bundle.getString("examiddetails");
