Question

我只是尝试启动我的程序，但似乎很难通过此错误。我做了一些研究，似乎与意图有关。我仔细检查了我的清单文件（将在下面发布），包名称似乎是正确的。

引起我注意的一件事是异常日志的第二行。正在寻找

class "com.project.BluetoothTransfer_v1000" on path:

在/data/app/com.project.BluetoothTransfer_v1000-1.apk

那应该是'-1'吗？

Answer 1

您在activity

中缺少Manifest.xml的名称

<activity
            android:name="com.project.BluetoothTransfer_v1000"

这是ClassNotFoundException：

的原因

 Caused by: java.lang.ClassNotFoundException: Didn't find class "com.project.BluetoothTransfer_v1000.BluetoothTransferActivity" on path: /data/app/com.project.BluetoothTransfer_v1000-1.apk

将您的活动名称“BluetoothTransferActivity”添加到Manifest.xml：

 <activity
            android:name="com.project.BluetoothTransfer_v1000.BluetoothTransferActivity"

意图？类名不匹配路径
