问题
I have looked every where for an answer to this. I have found many solutions for this error but it's not working for me. I have just started working with android 3 days ago. It was going great until today. I am getting this error
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]
The solutions I have seen was about a capitol letter in the package tag/name. Mine does not have a capitol letter in it but I am still getting the error. Here is my Manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mycompany.myfirstapp">
<uses-sdk android:minSdkVersion="7" android:targetSdkVersion="18" />
<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>
I'm not sure what's going on. Please, I really want to learn.

回答1:
<meta-data
android:name="android.support.PARENT_ACTIVITY" />
A meta-data element always requires either an android:value or android:resource attribute.
Either remove this element altogether, or add a value to the element, for example:
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".MyActivity"/>
(The PARENT_ACTIVITY metadata helps in ancestral navigation.)
