颤振项目Android X迁移问题

问题描述

我刚刚创建了一个新的flutter项目，添加了一些插件，并且我将插件切换到了android x，因此我需要切换到android x.我尝试了所有不同的方法来迁移到android x，到目前为止，没有一种方法对我有用.现在，我什至不知道该怎么办，它是如此令人沮丧，为什么在自动创建新项目时不那么处理.可能在项目中使用了离子性.

I just created a new flutter project, added a few plugins and I'm getting the plugin switched to android x therefore i need to switch to android x. I've tried all the different ways of moving to android x and none has worked for me so far. Right now i don't even know what to do anymore, its so frustrating, why wouldn't flutter handle that when creating new projects automatically. Might be using ionic for the project.

推荐答案

在创建新项目时，只需遵循 @harsh'的答案，您就完成了.

As you are creating a new project, just follow @harsh 's answer and you're done.

但是，当我最近升级我的现有应用程序以使用新的插件时，我也必须迁移到AndroidX ...以及官方说明不起作用，它正在使用Android Studio迁移项目-提示未找到用法！".

However, as I recently upgraded my existing app to use new plugins, I had to migrate to AndroidX as well... and the default procedure in the official instructions didn't work, which is using Android Studio to migrate the project - it said "No usages found!".

所以我所做的是:

1. 将Android Studio更新为3.3
2. 尝试菜单重构">迁移到AndroidX
3. 获得未发现用法"(如果您设法在此处进行操作，请停止！完成！！)...实际上，您可以给尝试一下，然后继续)
4. 打开android/gradle.properties并添加

1. updated Android Studio to 3.3
2. tried menu Refactor > Migrate to AndroidX
3. got "No usages found" (if you manage to do it here instead, stop! you're done! ... actually, you can give this answer a try before continuing)
4. opened android/gradle.properties and added

android.useAndroidX=true
android.enableJetifier=true

1. 打开android/build.gradle并更改

• com.android.tools.build:gradle到版本3.3.0
• com.google.gms:google-services到版本4.2.0

• com.android.tools.build:gradle to version 3.3.0
• com.google.gms:google-services to version 4.2.0

打开android/app/build.gradle和

• 将compileSdkVersion更改为28
• 将android.support.test.runner.AndroidJUnitRunner替换为androidx.test.runner.AndroidJUnitRunner
• 将com.android.support.test:runner替换为androidx.test:runner:1.1.0
• 将com.android.support.test.espresso:espresso-core替换为androidx.test.espresso:espresso-core:3.1.0
• 仅此而已，但这是所需替换的完整列表

• changed compileSdkVersion to 28
• replaced android.support.test.runner.AndroidJUnitRunner to androidx.test.runner.AndroidJUnitRunner
• replaced com.android.support.test:runner to androidx.test:runner:1.1.0
• replaced com.android.support.test.espresso:espresso-core to androidx.test.espresso:espresso-core:3.1.0
• in my case that was it, but here's the complete list of required replacements

打开android/gradle/wrapper/gradle-wrapper.properties并将distributionUrl更改为https\://services.gradle.org/distributions/gradle-4.10.2-all.zip (您可能必须使用5.4.1，请参见下面的更新)

执行了flutter clean

这与我的预期相反，确实有效！ :)

And contrary to what I expected, IT WORKED! :)

当我使用应用程序签名将应用程序更新为波动性v1.9.1+hotfix.5时，我陷入了错误SigningConfig "release" is missing required property "storePassword"的困境，最后，它是上面第7步中的gradle版本.因此，现在我按照5.4.1 noreferrer> Wiki .

When updating my app to flutter v1.9.1+hotfix.5, as I use app signing, I was stuck with the error SigningConfig "release" is missing required property "storePassword" and in the end it was the gradle version from step 7 above. So now I'm using 5.4.1 as suggested in this wiki.

[android/gradle/wrapper/gradle-wrapper.properties]

distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.1-all.zip
