android - 我无法从 jar 文件调用 Activity

Question

我有这样的场景:我有一个包含 jar 文件的主项目(一个向主项目提供一些信息的辅助项目)。我按照这个 tuto 创建了 jar 文件然后将jar文件添加到/libs中的主项目中，然后将其添加到Build Path中。

当我从 jar 文件调用 Activity 时出现致命异常

这是日志

这就是我在主项目中调用 Activity 的方式

final Intent intent = new Intent();
        
        Button juego1Btn = (Button) findViewById(R.id.juego1Btn);
        
        juego1Btn.setOnClickListener(new OnClickListener() {
            
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                /*Intent intent = new Intent(getBaseContext(), Subscription.class);
                startActivity(intent);*/
                intent.setAction(Intent.ACTION_MAIN);
                intent.setClassName("com.XXX.YYY", "com.XXX.YYY.Subscription");
                intent.putExtra("code", codigo);
                intent.putExtra("keyword", keyword);
                startActivityForResult(intent, 1);
            }
        });

这是 list

<activity
            android:name="com.XXX.YYY.Subscription"
            android:label="@string/app_name">
</activity>

知道为什么我有这个异常吗？

非常感谢!!!

Answer 1

首先，com.XXX.YYY.Subscription需要是 com.telecoming.sms_payment.Subscription ，如果您的代码值得相信。

其次，不要创建你的 Intent那样，作为你的<activity>不声称支持ACTION_MAIN .将您的代码替换为:

    Button juego1Btn = (Button) findViewById(R.id.juego1Btn);

    juego1Btn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent intent = new Intent(WhateverYourActivityClassIsWhereYouAreRightNow.this, Subscription.class);
            intent.putExtra("code", codigo);
            intent.putExtra("keyword", keyword);
            startActivityForResult(intent, 1);
        }
    });

(将 WhateverYourActivityClassIsWhereYouAreRightNow 替换为此代码所在的 Activity 的名称)
