注意：需要自己去  https://www.foxitsoftware.com/products/sdk/register.php?product=MobilePDFSDK 申请最新的试用包，我Demo中的key已经过期了。

android下加入

sourceSets {
    main {
        jniLibs.srcDirs = ['libs']
    }
}

另外加入

repositories {
    flatDir {
        dirs 'libs'
 }
}

dependencies中加入：

compile(name: 'FoxitRDKUIExtensions', ext: 'aar')
compile fileTree(dir: 'libs', include: ['*.jar'])

还有需要加

compile 'com.android.support:recyclerview-v7:25.3.1'

完整的build.gradle文件如下：

apply plugin: 'com.android.application'
 
android {
    compileSdkVersion 25
    buildToolsVersion "25.0.3"
    defaultConfig {
        applicationId "com.foxit.amy.amytestrdk4"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets {
        main {
            jniLibs.srcDirs = ['libs']
        }
    }
}
 
repositories {
    flatDir {
        dirs 'libs'
    }
}
 
dependencies {
    compile(name: 'FoxitRDKUIExtensions', ext: 'aar')
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support:recyclerview-v7:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
}

接下来是库的初始化，设置UI 配置文件，并打开文档

private PDFViewCtrl pdfViewCtrl = null;
private RelativeLayout parent = null;
private UIExtensionsManager uiextensionsManager = null;
private PDFReader defaultPDFReader = null;

pdfViewCtrl = new PDFViewCtrl(this.getApplicationContext());
// Instantiate a PDFViewCtrl object
// Get the config file, and set it to UIExtensionsManager.
InputStream stream = this.getApplicationContext().getResources().openRawResource(R.raw.uiextensions_config);
UIExtensionsManager.Config config = new UIExtensionsManager.Config(stream);
uiextensionsManager = new UIExtensionsManager(this.getApplicationContext(), null,pdfViewCtrl, config);
uiextensionsManager.setAttachedActivity(this);
pdfViewCtrl.setUIExtensionsManager(uiextensionsManager);
defaultPDFReader = (PDFReader) uiextensionsManager.getPDFReader();
defaultPDFReader.onCreate(this,
pdfViewCtrl, savedInstanceState);
String path = "/mnt/sdcard/Download/JIRA.pdf";
defaultPDFReader.openDocument(path, null);
setContentView(defaultPDFReader.getContentView());

Activity中重载相应的事件

 需要重载Activity的onStart，onPause，onResume，onStop，onDestroy, onActivityResult, onConfigurationChanged, onKeyDown, onPrepareOptionsMenu事件，把PDF Reader的相应事件在这里重载执行。

@Override
protected void onStart() {
    super.onStart();
    if (defaultPDFReader == null)
        return;
    defaultPDFReader.onStart(this);
}
@Override
protected void onPause() {
    super.onPause();
    if (defaultPDFReader == null)
        return;
    defaultPDFReader.onPause(this);
}
 
@Override
protected void onResume() {
    super.onResume();
    if (defaultPDFReader == null)
        return;
    defaultPDFReader.onResume(this);
}
 
@Override
protected void onStop() {
    super.onStop();
    if (defaultPDFReader == null)
        return;
    defaultPDFReader.onStop(this);
}
 
@Override
protected void onDestroy() {
    this.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    if (defaultPDFReader != null)
        defaultPDFReader.onDestroy(this);
    super.onDestroy();
}
 
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (defaultPDFReader != null)
        defaultPDFReader.onActivityResult(this, requestCode, resultCode, data);
}
 
@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    if (defaultPDFReader == null)
        return;
    ((MainFrame) defaultPDFReader.getMainFrame()).updateSettingBar();
    defaultPDFReader.onConfigurationChanged(this, newConfig);
}
 
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (defaultPDFReader != null && defaultPDFReader.onKeyDown(this, keyCode, event))
        return true;
    return super.onKeyDown(keyCode, event);
}
 
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    if (defaultPDFReader != null && !defaultPDFReader.onPrepareOptionsMenu(this, menu))
        return false;
    return super.onPrepareOptionsMenu(menu);
}
