Question

美好的一天！

我有一个带有MainActivity的JAR文件。我已经创建了一个新的Android应用程序来测试Intent代码。下面是我的按钮代码。

public void doSomething(View v) {
    Intent i = new Intent(this, com.testing1234.apptest.MainActivity.class);
    startActivity(i);
}

com.testing1234.apptest是我的JAR文件。当我尝试运行它时，带有按钮的第一个表单出现。单击按钮以运行JAR文件后，应用程序将终止。

在logcat上显示错误“找不到类'com.testing1234.apptest.MainActivity'”

或者它不是不可能的？我确实确保将JAR文件包含在我的项目中。请帮我。请随时向我提供一些有用的提示。感谢。

我尝试了另一个JAR文件，下面是我的清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.wodota.test123"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="21" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name="com.viva.demo.MainActivity" />         
</application>


</manifest>

Answer 1

您需要将活动添加到清单。您要运行的每个Activity都必须添加到Manifest。

添加：

<activity android:name="com.testing1234.apptest.MainActivity" />

使用Android应用程序运行JAR MainActivity
