android - 错误 :Execution failed for task ':app:compileDebugAidl ProcessException

Question

我无法构建 Aidl 库。
错误:

Error:Execution failed for task ':app:compileDebugAidl'. java.lang.RuntimeException: com.android.ide.common.process.ProcessException: Error while executing
'D:\mysdk\Android\android-sdk\build-tools\22.0.1\aidl.exe' with arguments

dC:\Users\admin\AppData\Local\Temp\aidl6013369886374174489.d ...\dev\myaidllibrary\ICoffeeMakerRemoteService.aidl}

build.gradle:

apply plugin: 'com.android.library'
apply plugin: 'com.neenbedankt.android-apt'
android {
    compileSdkVersion 21
    buildToolsVersion '22.0.1'
    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:21.0.0'
    testCompile 'junit:junit:4.12'
    provided 'com.google.auto.value:auto-value:1.2-rc1'
    // needed for Android Studio
    apt 'com.google.auto.value:auto-value:1.2-rc1'
    apt 'com.ryanharter.auto.value:auto-value-parcel:0.2.0'
}

目录结构:

aidl->
ICoffeeMakerRemoteService.aidl
Ingredient.aidl
java->
Ingredient.java

我受困于这些，尝试过可能的解决方案。

Answer 1

我犯了同样的错误，但我改正了。我猜你想“通过 IPC 传递对象”，我也是。

我的问题是我错过了对象aidl中的包定义，例如Rect.aidl，所以请尝试将包添加到您的aidl文件中。

例如:

Rect.aidl

package android.graphics;  // important

// Declare Rect so AIDL can find it and knows that it implements
// the parcelable protocol.
parcelable Rect;
