【Android  Hybrid App】Cordova 之掃碼（二維碼）功能

Error: Failed to fetch plugin https://github.com/phonegap/phonegap-plugin-barcodescanner.git via registry.
Probably this is either a connection problem, or plugin spec is incorrect.
Check your connection and plugin name/version/URL.
Error: cmd: Command failed with exit code 1 Error output:

安裝後，開啟工程，缺少 com.google.zxing 庫

import com.google.zxing.client.android.CaptureActivity;
import com.google.zxing.client.android.encode.EncodeActivity;
import com.google.zxing.client.android.Intents;

/**
 * This calls out to the ZXing barcode reader and returns the result.
 *
 * @sa https://github.com/apache/cordova-android/blob/master/framework/src/org/apache/cordova/CordovaPlugin.java
 */
public class BarcodeScanner extends CordovaPlugin {
    public static final int REQUEST_CODE = 0x0ba7c0de;
 

未成功構建Zxing-master工程，所以為解決上述問題，解除安裝外掛。

1.1.4. 刪除外掛
cordova plugin remove phonegap-plugin-barcodescanner
解除安裝過程中遇到問題:

Uninstalling phonegap-plugin-barcodescanner from android
cp: copyFileSync: could not write to dest file (code=ENOENT):E:\workspace\zxing-master\zxing-client-android\zxing-lib\build.gradle

Subproject Path: CordovaLib
Subproject Path: ../../../zxing-master/zxing-client-android/zxing-lib
Error: ENOENT: no such file or directory, open 'E:\workspace\zxing-master\zxing-client-android\zxing-lib\build.gradle'

E:\workspace\ispecapp>cordova plugin remove phonegap-plugin-barcodescanner
Uninstalling phonegap-plugin-barcodescanner from android

Removing "phonegap-plugin-barcodescanner"
Removing plugin phonegap-plugin-barcodescanner from config.xml file...
Removing phonegap-plugin-barcodescanner from package.json

二、基於zxing-client-android 元件lib及example 實現

2.1 eclipse 匯入lib 工程（CaptureActivity）
2.1.1 Android 工程設定
設定 CaptureActivity 工程為Library。

2.1.2 引數配置

AndroidManifest.xml
許可權配置

<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.FLASHLIGHT"/>
<uses-permission android:name="android.permission.VIBRATE"/>

<uses-sdk android:minSdkVersion="14" android:targetSdkVersion="23" />

3.Android 工程專案屬性配置

3.2 呼叫 CaptureActivity 的Android 工程配置及Api呼叫
3.2.1 新增依賴（zxing-clinet-lib CaptureActivity工程） 
引用 CaptureActivity Library。

配置（AndroidManifest.xml） users-sdk 引數，同CaptureActivity Library配置

<uses-sdk android:minSdkVersion="14" android:targetSdkVersion="23" />

待續...
