我正在尝试将 PDFNet 库集成到我的 Android 应用程序中，如果您下载 SDK，您可以看到有一个项目 CompleteReader (PDFNetAndroid-6.7.0.42960\PDFNetAndroid\samples\PDFViewCtrlProjects\CompleteReader)
我想将此项目用作我的应用程序中的模块，因此我将 build.gradle “com.android.application” 更改为 “com.android.library”
这里是原始的 build.gradle:
description = 'This is a more complete demo app that showcases PDFViewCtrl and the Tools library and its controls.'
apply plugin: 'com.android.application'
repositories {
mavenCentral()
}
buildscript {
repositories {

classpath 'com.trello:victor:0.1.4'
}
}
apply plugin: 'com.android.application'

compile fileTree(include: '*.jar', dir: 'libs')

}
}

}
}
task setupSample(dependsOn: [copyLibsToSamples, copyJarToSamples, copyResources])

这个原始文件编译没有问题，但是随着库的更改它不会构建，所以我删除了我在某处读到的可能是问题的地方:
repositories {
mavenCentral()
}
好的，有了这个更改，构建似乎可以继续，我得到的下一个错误是以下两个无法解决的引用(当原始文件未被修改时，这一切都有效!!!):
compile 'com.jakewharton:butterknife:7.0.1'
compile 'com.tonicartos:superslim:0.4.13'
几天前我在这个文件中尝试了很多东西，但没有运气，我删除了所有不需要的部分，移动了 jcenter 和 mavencentral，添加了它们，删除了它们等等。
这是我当前的 build.gradle 也不起作用:
description = 'This is a more complete demo app that showcases PDFViewCtrl and the Tools library and its controls.'
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.0'
classpath 'com.trello:victor:0.1.4'
}
}
apply plugin: 'com.android.library'
apply plugin: 'com.trello.victor'
dependencies {
repositories {
mavenCentral()
jcenter()
}
compile fileTree(include: '*.jar', dir: 'libs')
compile project(':PDFViewCtrlTools')
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile project(':superslim-0.4.13')
compile 'com.jakewharton:butterknife:7.0.1'
}
android {
compileSdkVersion 23
buildToolsVersion "23.0.3"
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
res.srcDirs = ['res']
jniLibs.srcDirs = ['libs']
svg.srcDir 'src/main/svg'
}
}
lintOptions {
// If true, stop the gradle build if errors are found
abortOnError false
//ignore 'ValidFragment'
}
}
task wrapper(type: Wrapper) {
gradleVersion = '2.2'
}
我改变什么都没关系，模块无法编译，我得到任务 CompleteReader:compileDebugJavaWithJavac 的执行失败，并且没有生成 R，所以我得到了很多“需要常量表达式”。我再说一遍，在将“应用程序”更改为“库”之前一切正常，我可以在手机上安装项目等。
你有什么想法吗？我已经为此工作了 3 天，但没有运气!
最佳答案
似乎问题出在黄油刀上。
在 PDFNet Android SDK 的 future 版本中，为了方便用户，我们将在任何示例项目中删除黄油刀的使用。
同时，我们建议您在 CompleteReader 示例项目中删除对黄油刀的使用。为此:
compile 'com.jakewharton:butterknife:7.0.1'来自 CompleteReader 的 build.gradle文件 BaseFileAdapter.java 中更改 ContentViewHolder分类如下:static class ContentViewHolder extends RecyclerView.ViewHolder {
ImageView imageViewFileIcon;
ImageView imageViewFileLockIcon;
TextView textViewFileName;
TextView textViewFileInfo;
ImageView imageViewFavoriteIcon;
ImageView imageViewInfoIcon;
View infoButton;
@TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR1)
public ContentViewHolder(View itemView) {
super(itemView);
imageViewFileIcon = (ImageView) itemView.findViewById(R.id.file_icon);
imageViewFileLockIcon = (ImageView) itemView.findViewById(R.id.file_lock_icon);
textViewFileName = (TextView) itemView.findViewById(R.id.file_name);
textViewFileInfo = (TextView) itemView.findViewById(R.id.file_info);
imageViewFavoriteIcon = (ImageView) itemView.findViewById(R.id.favorite_icon);
imageViewInfoIcon = (ImageView) itemView.findViewById(R.id.info_icon);
infoButton = itemView.findViewById(R.id.info_button);
if (Utils.isJellyBeanMR1() && textViewFileName != null && textViewFileInfo != null) {
// instead of creating a different layout for v17 we set alignment in the code:
if (textViewFileName.getGravity() != Gravity.CENTER) {
textViewFileName.setTextAlignment(View.TEXT_ALIGNMENT_VIEW_START);
}
textViewFileName.setTextDirection(View.TEXT_DIRECTION_LTR);
textViewFileInfo.setTextDirection(View.TEXT_DIRECTION_LOCALE);
}
}
}
