Android 拆分安装错误 (-2)：Module_Unavailable 错误

问题描述

我正在尝试在我的 android 应用中实现按需交付功能。现在我正在研究示例以了解它是如何工作的，但是当我尝试安装动态模块时，它显示一条错误消息“拆分安装错误（-2）：请求的模块不可用（对于此用户/设备，对于已安装的apk）。(https://developer.android.com/reference/com/google/android/play/core/splitinstall/model/SplitInstallErrorCode.html#MODULE_UNAVAILABLE)"

我看过很多例子，也遵循了 google 的拆分安装文档，我也看过很多 StackOverflow 问题/答案，但我找不到任何解决方案。

我的代码

MainActivity.java（基础应用）：

    download = findViewById(R.id.download);



    splitInstallManager = SplitInstallManagerFactory.create(getApplicationContext());

    download.setonClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            downloadDynamicModule();

    });






}

    Splitinstallrequest request = Splitinstallrequest.newBuilder().addModule("dynamic").build();

                    case SplitInstallSessionStatus.DOWNLOADING:
                        Toast.makeText(MainActivity.this,"Dynamic Module downloading",Toast.LENGTH_SHORT).show();
                        // Update progress bar.
                        break;

            else{

            }
        }
    };

    splitInstallManager.registerListener(listener);

    splitInstallManager.startInstall(request).addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(Exception e) {

                }
            })
            .addOnSuccessListener(new OnSuccessListener<Integer>() {
                @Override
                public void onSuccess(Integer sessionId) {
                    mySessionId = sessionId;
                    Toast.makeText(MainActivity.this,"Success"+sessionId,Toast.LENGTH_SHORT).show();
                }
            });

我已将运行配置编辑为“来自应用程序包的 Apk”，我正在通过内部测试跟踪测试应用程序，但它不起作用。

解决方法

转到 Run > Edit configurations 并选择 Default APK，或确保您的所有模块都如图所示进行了检查。
