Question

我有一个运行良好的应用程序。现在，我需要添加Firestore功能，但无法构建。控制台错误：

Launching lib\main.dart on Phone in debug mode...
Configuration 'compile' in project ':app' is deprecated. Use 
'implementation' instead.
registerResGeneratingTask is deprecated, use 
registerGeneratedFolders(FileCollection)
registerResGeneratingTask is deprecated, use 
registerGeneratedFolders(FileCollection)
registerResGeneratingTask is deprecated, use 
registerGeneratedFolders(FileCollection)

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task 
':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
> java.lang.RuntimeException: java.lang.RuntimeException: 
com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or -- 
debug option to get more log output.

* Get more help at https://help.gradle.org

BUILD FAILED in 2m 3s
Gradle build failed: 1

在 app / build.gradle

中添加行implementation 'com.google.firebase:firebase-firestore:17.1.0'后出现错误

dependencies {
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso- 
core:3.0.1'
compile 'com.google.firebase:firebase-core:16.0.3'
implementation 'com.google.firebase:firebase-auth:16.0.3'
implementation 'com.google.firebase:firebase-firestore:17.1.0'  //if I comment out this line the app compiles and builds normally. 
//Also I can use FirebaseAuth in the app so I don't think I have wrongly configured Firebase
}

我什至尝试在Android Studio中运行它，但还是一无所获。添加其他依赖项，例如cloud storage和cloud messaging，应用程序将正常构建。但是在添加firestore行之后，就会出现错误

最后还是在Stackoverflow的另一篇文章中找到了答案这些代码行应添加到build.gradle文件（模块：app）中。

private void alignTopRight(ImageView imageView)
{
    imageView.setScaleType(ImageView.ScaleType.MATRIX); // !

    final int drawableWidth = imageView.getDrawable().getIntrinsicWidth();
    final int viewWidth = imageView.getWidth();
    Matrix matrix = new Matrix();
    matrix.postTranslate(viewWidth-drawableWidth, 0);
    imageView.setImageMatrix(matrix);
}

private void alignBottomLeft(ImageView imageView)
{
    imageView.setScaleType(ImageView.ScaleType.MATRIX); // !

    final int drawableHeight = imageView.getDrawable().getIntrinsicHeight();
    final int viewHeight = imageView.getHeight();
    Matrix matrix = new Matrix();
    matrix.postTranslate(0, viewHeight-drawableHeight);
    imageView.setImageMatrix(matrix);
}

Firestore依赖性错误波动
