问题描述

我正在尝试编译我的Project，但是有一些错误

I'm trying to compile my Project,but in there is some error

Android manifest.xml

Android manifest.xml

 <application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

我已经尝试重建项目或与gradle同步，但是它对我不起作用.

I already try to rebuild project or sync with gradle but it's not working for me.

我的依赖项

compile 'com.android.support:appcompat-v7:23.0.0'
compile 'com.android.support:design:23.0.0'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'
compile project(':circleimageview-2.0.0-sources')

如何解决此错误?我是Android Studio的新手.

How to fix this error? I'm newbie to Android Studio.

推荐答案

roundIcon是

roundIcon is an attribute that was first introduced for Android Nougat 7.1 (API level 25), therefore you have two available options based on the type of device you're targeting:

• 如果您要构建专门针对Android 7.1或更高版本的应用，请确保在应用的build.gradle中将minSdkVersion和targetSdkVersion设置为25:

• If you're building an app specifically for Android 7.1 or above, ensure that minSdkVersion and targetSdkVersion are set to 25 in your app's build.gradle:

defaultConfig {
    minSdkVersion 25
    targetSdkVersion 25
}

---

• 或者，如果要定位较旧的API级别，则需要从清单中删除android:roundIcon，而仅使用android:icon.

---

• Alternatively, if you want to target older API levels, you will need to remove android:roundIcon from your manifest and only use android:icon.
