在尝试调试我的应用程序时，在我的三星Galaxy S4上，我得到了以下输出：
Waiting for device.
Target device: samsung-samsung_sgh_i337-8c8aa2c7
Uploading file
local path: C:\Users\awebberley\AndroidStudioProjects\Contacts\app\build\apk\app-debug-unaligned.apk
remote path: /data/local/tmp/org.intracode.contacts
Installing org.intracode.contacts
DEVICE SHELL COMMAND: pm install -r "/data/local/tmp/org.intracode.contacts"
pkg:/data/local/tmp/org.intracode.contacts
Success
Waiting for process: org.intracode.contacts
应用程序一直停留在“等待进程”消息，没有运行应用程序。 我是Android开发的新手，我错过了什么吗？
顺便说一下，在此之前我能够在模拟器中启动该应用程序，但是在尝试后并返回到模拟器后，出现了相同的“等待进程”消息。
这是我的manifest.xml文件：
<?xml version="1.0" encoding="utf-8"?>
<application
android:debuggable="true"
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="org.intracode.contacts.MainActivity"
android:launchMode="standard"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
这是我的唯一 Java 文件：

addBtn.setOnClickListener(new View.OnClickListener() {

}
});
nameTxt.addTextChangedListener(new TextWatcher() {
@Override

}
@Override

}
@Override

});
}
@Override

// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
谢谢
