Question

我尝试使用TWA [https://developers.google.com/web/updates/2019/02/using-twa][1]将pwa应用程序转换为android应用程序。我遵循了所有步骤。当我单击Build并使用android模拟器运行应用程序时，出现错误

我检查了很多资源[Android App Startup Crash - customtabs.CustomTabsSession.validateRelationship。但是问题没有解决

Answer 1

我遇到了同样的问题，问题似乎出在对androidx库的依赖以及最新版本的custom-tabs-client的依赖上。

事实证明，我们应该使用androidx.browser和android-browser-helper而不是custom-tabs-client

build.gradle：

implementation 'androidx.browser:browser:1.0.0'
implementation 'com.github.GoogleChrome:android-browser-helper:ff8dfc4ed3d4133aacc837673c88d090d3628ec8'

Answer 2

我意识到有太多的变体会碰到或错过，但这就是我在build.gradle中放的内容：

dependencies {

// From a combination of:
//  https://medium.com/@elliatab/trusted-web-activities-for-android-developers-4d8dea3dac9a
// and
//  https://developers.google.com/web/updates/2019/02/using-twa

implementation fileTree(dir: 'libs', include: ['*.jar'])

implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
//implementation 'com.android.support:design:28.0.0'

implementation 'com.github.GoogleChrome:custom-tabs-client:7ab7178ae0c4858d15b1918bded4dd5cac758870'

testImplementation 'junit:junit:4.12'}

上述错误消失了。在Android 4.4和Android 9上均可使用。
