Android工程：Google - play pass:应用要求

设备/引擎：Mac（11.6）/cocos

开发工具：Android studio（4.1.2）

开发需求：根据Google-Play Pass要求更改代码

1.在工程->app->build.gradle中添加SDK

implementation 'com.github.google:play-licensing:-SNAPSHOT'

2.工程->build.gradle中添加

maven {
   url 'https://jitpack.io'
}

3.在AndroidManifest.xml下添加

<uses-permission android:name="com.android.vending.CHECK_LICENSE" />

4.添加strings值：

<!-- License checking status messages -->
<string name="check_license">Check license</string>
<string name="checking_license">Checking license...</string>
<string name="dont_allow">Don\'t allow the user access</string>
<string name="allow">Allow the user access</string>
<string name="application_error">Application error: %1$d</string>
<string name="setting_tips_title">Choose an activity</string>
<string name="setting_tips_message">Please choose at least 1 activity to play.</string>

<!-- Unlicensed dialog messages -->
<string name="unlicensed_dialog_title">Application not licensed</string>
<string name="unlicensed_dialog_body">This application is not licensed.</string>
<string name="unlicensed_dialog_retry_body">Unable to validate license. Check to see if a network connection is available.</string>
<string name="restore_access_button">Restore Access</string>
<string name="retry_button">Retry</string>
<string name="quit_button">Exit</string>

5.修改状态栏颜色（一般会要求修改为浅色）
1）在color.xml下修改

<color name="colorAccent">#3F51B5</color>

2）在styles.xml下修改

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

6.找到工程的Cocos2dxActivity.java添加如下代码

import com.google.android.vending.licensing.AESObfuscator;
import com.google.android.vending.licensing.LicenseChecker;
import com.google.android.vending.licensing.LicenseCheckerCallback;
import com.google.android.vending.licensing.Policy;
import com.google.android.vending.licensing.ServerManagedPolicy;

1）在public abstract class Cocos2dxActivity extends Activity implements Cocos2dxHelperListener中添加

	private static final String BASE64_PUBLIC_KEY = "在google后台自己对应的app中查找";
	// Generate your own 20 random bytes, and put them here.
	private static final byte[] SALT = new byte[]{"用电脑终端生成"};

	private LicenseChecker mCHecker;
	private LicenseCheckerCallback mLicenseCheckerCallback;
	public ServerManagedPolicy mServerManagedPolicy;
	public static String STORAGE_NAME = "Dr.Dino";
	public static String LISEN_KEY = "LicenseStatus";
	public boolean isLicensed = false;

SALT值可以通过终端输入：python -c "import random; print ', '.join(str(random.randint(-128, 127)) for x in xrange(20))"来生成

2）在public static Context getContext()中添加

String deviceId = Settings.Secure.getString(getContentResolver(), Settings.Secure.ANDROID_ID);

mLicenseCheckerCallback = new MyLicenseCheckerCallback();
//    	mServerManagedPolicy = new ServerManagedPolicy(this,new AESObfuscator(SALT, getPackageName(),deviceId));
mCHecker = new LicenseChecker(this,new ServerManagedPolicy(this,new AESObfuscator(SALT, getPackageName(),deviceId)),BASE64_PUBLIC_KEY);
doCheck();

3）在onResume、onPause、onDestroy中分别添加

if (this.mGLSurfaceView != null){
	this.mGLSurfaceView.onResume();
}

if (this.mGLSurfaceView != null){
	this.mGLSurfaceView.onPause();
}

mCHecker.onDestroy();

4）添加如下代码

public void checkCacheAllowCallback(){
		if (isLicensed){
			JoyPreschool.onLicenseCallback();
		}else {
			displayDialog(Policy.NOT_LICENSED == Policy.RETRY);
			doCheck();
		}
	}

public void doCheck(){

		mCHecker.checkAccess(mLicenseCheckerCallback);
	}

	protected Dialog onCreateDialog(int id) {
		final boolean bRetry = id == 1;
		AlertDialog alertDialog = new AlertDialog.Builder(this)
				.setTitle(R.string.unlicensed_dialog_title)
				.setMessage(bRetry ? R.string.unlicensed_dialog_retry_body : R.string.unlicensed_dialog_body)
				.setPositiveButton(bRetry ? R.string.retry_button : R.string.restore_access_button,
						new DialogInterface.OnClickListener() {
							boolean mRetry = bRetry;
							public void onClick(DialogInterface dialog, int which) {
								if ( mRetry ) {
									doCheck();
								} else {
									mCHecker.followLastLicensingUrl(Cocos2dxActivity.this);
									System.exit(0);
								}
							}
						})
				.setNegativeButton(R.string.quit_button, new DialogInterface.OnClickListener() {
					public void onClick(DialogInterface dialog, int which) {
						System.exit(0);
					}
				}).create();

//		alertDialog.getButton(DialogInterface.BUTTON_POSITIVE).setGravity(Gravity.CENTER);
//		alertDialog.getButton(DialogInterface.BUTTON_POSITIVE).setWidth(250);
//		alertDialog.getButton(DialogInterface.BUTTON_NEGATIVE).setWidth(250);
		return alertDialog;
	}


public void displayDialog(final boolean showRetry) {
		mHandler.post(new Runnable() {
			public void run() {
				setProgressBarIndeterminateVisibility(false);
				showDialog(showRetry ? 1 : 0);
			}
		});
	}

public void setPassStatus(Context context,int _keyValue)
	{
		SharedPreferences _sp = context.getSharedPreferences(STORAGE_NAME,context.MODE_PRIVATE);

		SharedPreferences.Editor editor = _sp.edit();

		editor.putInt(LISEN_KEY,_keyValue);

		editor.commit();

	}

private class MyLicenseCheckerCallback implements LicenseCheckerCallback {
		public void allow(int policyReason){
			if (isFinishing()) {
				// Don't update UI if Activity is finishing.
				return;
			}
			// Should allow user access.
			Log.d(TAG, "policyReason=" + policyReason);
			isLicensed = true;

//			if (mServerManagedPolicy != null){
//				long ts = System.currentTimeMillis();
//				if (ts <= mServerManagedPolicy.getValidityTimestamp()) {
//					Log.d(TAG, "getValidityTimestamp=" + mServerManagedPolicy.getValidityTimestamp());
//					// Cached LICENSED response is still valid.
//				}
//			}
//			setPassStatus(sContext,policyReason);
		}

		@Override
public void dontAllow(int reason) {
			if (isFinishing()) {
				// Don't update UI if Activity is finishing.
				return;
			}
			Log.d(TAG, "dontAllow reason=" + reason);
			isLicensed = false;
//			setPassStatus(sContext,reason);
			if (reason != Policy.RETRY){
				mCHecker.followLastLicensingUrl(sContext);
				Cocos2dxActivity.this.finish();
			}else {

				displayDialog(reason == Policy.RETRY);
			}
		}

		@Override
public void applicationError(int errorCode) {

			if (isFinishing()) {
				// Don't update UI if Activity is finishing.
				return;
			}
			isLicensed = false;
			Log.d(TAG, "errorCode=" + errorCode);
//			if (mServerManagedPolicy != null){
//				if (mServerManagedPolicy.allowAccess()){
//					JoyPreschool.onLicenseCallback();
//				}else {
//
//					String result = String.format(getString(R.string.application_error), errorCode);
//					CharSequence charResult = result;
//					Toast.makeText(sContext,charResult,Toast.LENGTH_SHORT).show();
//				}
//			}
			mCHecker.followLastLicensingUrl(sContext);
			System.exit(0);
//			JoyPreschool.joylandInstance.checkLocalLicense();
		}

		;
}

7.在工程的Activity.java下添加

import com.google.android.vending.licensing.LicenseChecker;
import com.google.android.vending.licensing.LicenseCheckerCallback;
import com.google.android.vending.licensing.Policy;

public void checkLocalLicense(){
//        SharedPreferences _sp = Cocos2dxActivity.getContext().getSharedPreferences(STORAGE_NAME,Cocos2dxActivity.getContext().MODE_PRIVATE);
//        if (_sp != null){
//            int curReason = _sp.getInt(LISEN_KEY,Policy.RETRY);
//            if (curReason == Policy.LICENSED){
//                JoyPreschool.onLicenseCallback();
//            }else {
//
//                Cocos2dxActivity.instance.displayDialog(curReason == Policy.RETRY);
//            }
//        }
        Cocos2dxActivity.instance.checkCacheAllowCallback();
}

public static native void onLicenseCallback();
