android - Android 中的自定义隐式 Intent 不起作用

Question

我正在测试隐式 Intent 。我有两个小型测试应用程序: 第一个 AndroidManifest.xml:

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

    <uses-sdk android:minSdkVersion="14" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:label="@string/app_name"
            android:name="com.sudipta.example.Intent1Activity" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <intent-filter >
                <action  android:name="com.sudipta.personal.TEST" />
                <category android:name="android.intent.category.DEFAULT" />
                <data android:mimeType="text/plain"/>
            </intent-filter>
        </activity>
    </application>

</manifest>

第二个 AndroidManifest.xml:

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

    <uses-sdk android:minSdkVersion="14" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:label="@string/app_name"
            android:name=".Intent2Activity" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <intent-filter >
                <action  android:name="com.sudipta.personal.TEST" />
                <category android:name="android.intent.category.DEFAULT" />
                <data android:mimeType="text/plain"/>
            </intent-filter>
        </activity>
    </application>

</manifest>

现在我调用下面的代码:

btn1.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                //Call the Implicit Intent
                Intent intent = new Intent();
                intent.setAction("com.sudipta.personal.TEST");
                startActivity(intent);                      
            }
        });

下面是我收到的错误代码:

你能告诉我这里的问题是什么吗？谢谢。

后记。

尝试从您尝试启动的 Activity 中删除 android:label。也许它无法访问 app_name 字符串
