Hello World 应用程序在 2.3.3 (API 10) 上崩溃，但在 5.1 (API 22) 上运行良好

Question

使用Android Studio，我创建了一个非常基本的骨架应用程序。它适用于 android 5.1 API 22，但在 android 2.3.3 API 10 上调用时崩溃。

这是崩溃日志。它显示abc_vector_test.xml文件的资源未找到异常。

我已经尝试了一些方法(见下面的代码)。 文件是：

import android.support.v7.widget.Toolbar;

// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);

}
@Override

// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.

return true;
}
return super.onOptionsItemSelected(item);
}
}

应用程序的 build.gradle 文件：

apply plugin: 'com.android.application'
android {

defaultConfig {
applicationId "com.myco.k5"
minSdkVersion 10

testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:design:25.3.1'
compile 'com.android.support:multidex:1.0.1'
}
Top level build.gradle file:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.3.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}

请就如何解决此崩溃提供建议。

已解决：使用以下方法解决此问题

1. 在应用程序级别使用构建.gradle 文件

   安卓 {
   //您在此处
   生成的条目密度 = [] } 标志通知 aapt 保留属性 ID 周围 aaptOptions { 附加参数 "--no-version-vectors" }

   2. 在顶级 build.gradle 文件中将类路径从 1.4.0 更改为 1.5.0

类路径 'com.android.tools.build：gradle：1.5.0' 早些时候这里是 1.4.0

Answer 1

在您的情况下，您必须启用矢量可绘制对象才能在旧的 android 版本中使用它。将其添加到build.gradle文件(模块应用)中。

对于 Gradle 插件 2.0+

android {
defaultConfig {
vectorDrawables.useSupportLibrary = true
}
}

对于 Gradle 插件 1.5 或更低

版本

android {
defaultConfig {
// Stops the Gradle plugin’s automatic rasterization of vectors
generatedDensities = []
}
// Flag notifies aapt to keep the attribute IDs around
aaptOptions {
additionalParameters "--no-version-vectors"
}
}

完成此操作后，您必须更改ImageView才能像这样使用兼容 src：

<ImageView
app:srcCompat="@drawable/abc_vector_test"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
