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上的调用时崩溃。

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（参见下面的代码）。文件是：

的AndroidManifest.xml：

<?xml version="1.0" encoding="utf-8"?>

package="com.myco.k5" >

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

</manifest>

activity_main.xml中：

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

    @Override

        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // 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.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement

            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

app的build.gradle文件：

    apply plugin: 'com.android.application'

    android {
        compileSdkVersion 25
        buildToolsVersion "23.0.1"

        defaultConfig {
            applicationId "com.myco.k5"
            minSdkVersion 10
            targetSdkVersion 25
            versionCode 1
            versionName "1.0"
            multiDexEnabled true
        }
        dexOptions {
            incremental true
            javaMaxHeapSize "4g"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
    }

    dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        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
    }

请告知如何解决此崩溃。

已解决：使用以下

解决了这个问题

在app级别的build.gradle文件中使用

android {
//你的参赛作品
generatedDensities = [] } // Flag通知aapt保留属性ID aaptOptions { additionalParameters“--no-version-vectors” }
1. 在顶级build.gradle文件中，将classpath从1.4.0更改为1.5.0

classpath'com.android.tools.build：grad：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Vector Drawable才能在旧的Android版本中使用它。将其添加到build.gradle文件（模块应用程序）中。

Gradle Plugin 2.0 +

android {
       defaultConfig {
         vectorDrawables.useSupportLibrary = true
        }
     }

适用于Gradle Plugin 1.5或以下

 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"
      }
    }

执行此操作后，您必须更改ImageView以使用compat src：

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