我无法从jar文件中调用活动

标签: android jar activitynotfoundexception

我有这样的场景:我有一个主项目有一个jar文件(一个辅助项目,它给主要的一些信息)。我在这个tuto中创建了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文件中调用活动时,会出现致命异常

这是logCat

这就是我在主项目中调用活动的方式

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);
            }
        });

这是清单

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

我为什么会遇到这种异常?

非常感谢!!!

首先,com.XXX.YYY.Subscription需要com.telecoming.sms_payment.Subscription,如果您的代码是相信的话。

其次,请勿以Intent方式创建<activity>,因为ACTION_MAIN并未声明支持 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); } }); 。用以下代码替换您的代码:

WhateverYourActivityClassIsWhereYouAreRightNow

(将Activity替换为此代码所在的{{1}}的名称)

问题在于我创建库的方式,通过一步一步跟随这个tuto它工作正常http://es.slideshare.net/ajdgeniz/como-hacer-un-archivo-jar-en-eclipse
