logcat警告`< manifest>：meta-data`下的未知元素是什么意思？ [英] What does the logcat warning `Unknown element under <manifest>: meta-data` mean?

问题描述

在运行新安装的应用程序时，我在logcat中发现了 Warning 消息：

While running a a freshly installed app, I find this Warning messages in the logcat:

W/PackageManager( 1233): Couldn't remove dex file for package:  at location /data/app/xx.yy.zz-1/base.apk, retcode=-1
I/SmartHeartBeat( 1233): listenAppUpdate, package: xx.yy.zz has been Updated
W/PackageParser( 2909): Unknown element under <manifest>: meta-data at /storage/emulated/0/xxx/zz.apk Binary XML file line #143

试图追查违规的元数据元素标记为二进制XML文件行＃143 ，我找到以下内容：

Trying to track down the offending meta-data element tagged Binary XML file line #143, I find the following:

# aapt l -a zz.apk

AndroidManifest.xml
META-INF/CERT.RSA
META-INF/CERT.SF
META-INF/MANIFEST.MF
...
Android manifest:
N: android=http://schemas.android.com/apk/res/android
  E: manifest (line=2)
    ...
    A: platformBuildVersionCode=(type 0x10)0x19 (Raw: "25")
    A: platformBuildVersionName="7.1.1" (Raw: "7.1.1")
    ...
    E: meta-data (line=143)
      A: android:name(0x01010003)="android.support.VERSION" (Raw: "android.support.VERSION")
      A: android:value(0x01010024)="25.3.1" (Raw: "25.3.1")
...

但我在 AndroidManifest中没有这样的东西。 xml ，唯一对25.3.1的引用是在我的 gradle.build 文件中，它们是 Android支持库：

But I don't have anything like this in my AndroidManifest.xml and the only other reference to "25.3.1" is in my gradle.build file, which are the dependency lines for the Android Support Libraries:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-v4:25.3.1'
    ...
}

出现此问题的原因是什么？
（我如何解决此问题？ p>

What is the problem and why does this warning occur? (How do I resolve it?)

推荐答案

关闭 即时运行 功能可以解决问题。

Turning off instant run feature would resolve the issue.
