您好，麻烦提供详细的报错信息

我写了

ndk {
    abiFilters 'armeabi-v7a','x86','x86-64'
}以后

又报错了

Installation did not succeed.
The application could not be installed: INSTALL_FAILED_NO_MATCHING_ABIS

List of apks:
[0] 'D:\SuperMapiMobile3D\app\build\outputs\apk\debug\app-debug.apk'
Installation failed due to: 'INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries, res=-113'
这是错误原因

    splits {
        abi {

            reset()
            include 'x86', 'armeabi-v7a', 'x86-64'
            universalApk true

    }

    }
    sourceSets {
        main{
            jniLibs.srcDirs=['libs']
        }
    }


    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
}

写了ndk后还是有错误 然后百度写了

splits {
    abi {
        enable true
        reset()
        include 'x86', 'armeabi-v7a', 'x86-64'
        universalApk true
    }

然后又报错

    java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.supermapimobile3d/com.example.supermapimobile3d.MainActivity}: java.lang.NullPointerException: Attempt to get length of null array

at com.example.supermapimobile3d.MainActivity.onCreate(MainActivity.java:24)还是这行报错

你那边看下libs里面的so文件的文件夹名称是啥？ndk里面就设置这个文件夹名称

---

是armeabi-v7a  那还需要x86吗

---

不需要了，只设置armeabi-v7a 就可以
