AndroidStudio打开其他ADT Project（比如e

工作需要，尝试运行第三方SDK的demo，但是它是eclipse ADT，用Android Studio导入后，报以下错误：

1、Could not find com.android.tools.build:gradle:7.0.2.

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'RegoDemo'.
> Could not resolve all artifacts for configuration ':classpath'.
   > Could not find com.android.tools.build:gradle:7.0.2.
     Searched in the following locations:
       - https://jcenter.bintray.com/com/android/tools/build/gradle/7.0.2/gradle-7.0.2.pom
     If the artifact you are trying to retrieve can be found in the repository but without metadata in 'Maven POM' format, you need to adjust the 'metadataSources { ... }' of the repository declaration.

解决方法：在project根目录的build.gradle添加google()：

buildscript {
    repositories {
        google()
        ...
    }
}

allprojects {
    repositories {
        google()
        ...
    }
}

如下：

2、Could not find method compile() for arguments [file collection]

A problem occurred evaluating project ':app'.
> Could not find method compile() for arguments [file collection] 
on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.
at build_9zrx3shc94jmbsa4m7q46jpc6$_run_closure2.doCall
(/Users/didi/AndroidStudioProjects/PrintDemo/RegoDemo/app/build.gradle:22)

app/build.gradle 报错代码如下：

dependencies {
    compile files('libs/regoPrintLibV03.02.09.jar')
}

解决方法：将以上代码换成以下代码：

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation files('libs/regoPrintLibV03.02.09.jar')
}

3、AAPT: error: '@+array/comName' is incompatible with attribute entries (attr) reference.

错误代码如下：

<Spinner
            android:id="@+id/spinner_porttype"
            android:layout_width="match_parent"
             android:layout_height="wrap_content"
            android:layout_toRightOf="@id/Text_porttype"
            android:entries="@+array/Interface" />

解决方法：去掉array前面的+号即可：

<Spinner
            android:id="@+id/spinner_porttype"
            android:layout_width="match_parent"
             android:layout_height="wrap_content"
            android:layout_toRightOf="@id/Text_porttype"
            android:entries="@array/Interface" />
