The above is the source file

我在清单 xml 中有以下内容

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myimagematchgamev10"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="7"
        android:targetSdkVersion="10" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.myimagematchgamev10.MainActivity"
            android:label="@string/app_name" >

            </intent-filter>
        </activity>
    </application>

</manifest>

以上是manifest xml

【问题讨论】：

简单。 LogcatNotFoundException。 @Enrichman 哈哈不错。 @Enrichman 也可能是 LogcatNotPostedException ;-) 巨魔，大声笑......重点是你应该发布 logcat targetSdkVersion="10" o_O 【参考方案1】：

据我所知，没有日志，您使用的是在 Gingerbread 之后引入的 API。

只需阅读 LogCat，它应该会为您提供有关不起作用的确切功能的提示。
