在我的Android应用程序中,我试图在我的谷歌应用引擎后端服务器上验证谷歌令牌.但我总是得到这个例外:
com.google.android.gms.auth.GoogleAuthException: getToken(Unknown Source) exception
我的代码:
private Account mAccount = AccountManager.get(this).getAccountsByType(GoogleAuthUtil.GOOGLE_ACCOUNT_TYPE)[0];
private static final String SCOPE = "audience:server:client_id:" +Constants.WED_CLIENT_ID;
String token = GoogleAuthUtil.getToken(LoginActivity.this, mAccount.name, SCOPE);
我已经尝试了Stackoverflow中提出的每个解决方案.
自从2天以来,我一直在努力解决这个问题.我已成功通过可下载内容实施In App购买.但每当我删除应用程序并恢复购买时,恢复实际上并不下载内容.但是,如果我在restoreTransaction中添加下载代码,它永远不会调用完成事务,导致应用程序表现得很奇怪(这是合理的),每次我删除应用程序并重新安装它.任何帮助表示赞赏!! 如果有人需要进一步解释,请告诉我.谢谢!!

我想在我的项目中添加Facebook SDK.在我的项目 - > properties-> Android下添加它(然后添加facebook adk作为库),当我尝试创建我的xml文件并使用它显示我旁边的红十字会,无论我做什么,我都无法让这个错误消失.请帮帮我.感谢任何帮助!!
我正在使用这个扩展另一个抽象类的类A(这个抽象类扩展了FragmentActivity)和我在A类中的一个函数中我希望得到当前活动A的getActivity().但每当我使用getActivity时,它给出我错误,getActivity()方法没有为我的类定义类型.请帮我 !!我怎么能实现这个？
我的班级代码A.
public class A extends B
{
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.voicing);
//doing another initializations and stuff//
}
}
B类代码
public abstract class B extends FragmentActivity
{
FragmentAdapter mAdapter;
ViewPager mPager;
PageIndicator mIndicator;
}
我正在使用SKShapeNode创建一个类似山的对象.我使用CGMutablePathRef来指向我的路径
SKShapeNode *shapenode = [[SKShapeNode alloc] init];
CGMutablePathRef path = CGPathCreateMutable();
CGPathMoveToPoint(path, NULL, 0, 0);
......
for (int i = 0; i < [refData count];i++) {
CGPathAddLineToPoint(path, NULL, ((float)i/[refData count])*screenWidthBoundry, [[refData objectAtIndex:i] doubleValue]);
}
CGPathAddLineToPoint(path, NULL, screenWidthBoundry, 0);
CGPathAddLineToPoint(path, NULL, 0, 0);
shapenode.path = path;
shapenode.antialiased = YES;
shapenode.fillColor = [SKColor colorWithRed:17.0/255.0 green:108.0/255.0 blue:125.0/255.0 alpha:1.0];
//shapenode.strokeColor = [UIColor clearColor];
shapenode.lineWidth = 1.0f;
shapenode.physicsBody = [SKPhysicsBody bodyWithEdgeChainFromPath:path];
shapenode.physicsBody.affectedByGravity = NO;
shapenode.physicsBody.categoryBitMask = CollisionTypeMountain;
shapenode.physicsBody.collisionBitMask = 0;
shapenode.physicsBody.contactTestBitMask = CollisionTypeBird;
CGPathRelease(path);
return …
