Question

我已经找到了答案的每个地方。我已经为这个错误找到了许多解决方案，但它对我不起作用。我3天前刚刚开始使用android。它一直很好，直到今天。我收到此错误

Installing com.mycompany.myfirstapp
DEVICE SHELL COMMAND: pm install -r "/data/local/tmp/com.mycompany.myfirstapp"
pkg: /data/local/tmp/com.mycompany.myfirstapp
Failure [INSTALL_PARSE_FAILED_MANIFEST_MALFORMED]

我见过的解决方案是关于包装标签/名称中的国会大厦字母。我没有国会大厦的信，但我仍然得到错误。这是我的清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.mycompany.myfirstapp">

        <application
            android:allowBackup="true"
            android:icon="@mipmap/ic_launcher"
            android:label="@string/app_name"
            android:theme="@style/AppTheme" >
            <activity
                android:name=".MyActivity"
                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=".DisplayMessageActivity"
                android:label="@string/title_activity_display_message"
                android:parentActivityName=".MyActivity" >
                <meta-data
                    android:name="android.support.PARENT_ACTIVITY" />
            </activity>
        </application>
    </manifest>

我不确定发生了什么。拜托，我真的很想学。

Answer 1

<meta-data
    android:name="android.support.PARENT_ACTIVITY" />

meta-data元素始终需要android:value或android:resource属性。

完全删除此元素，或向元素添加值，例如：

<meta-data
    android:name="android.support.PARENT_ACTIVITY"
    android:value=".MyActivity"/>

（PARENT_ACTIVITY元数据有助于ancestral navigation。）
