我与有例外Google Play结算库 v3。 我在onDestroy活动方法释放帐单客户端。Android结算v3 - BillingClientImpl.java:668处的NullPointerExceptionException
有没有人有此问题?

计费客户端连接调用的代码:
private com.android.billingclient.api.BillingClient billingClient;
public AppBillingManager(Context context) {
billingClient = new BillingClient.Builder(context)
.setListener(this)
.build();
}
public void doConnect(final Runnable postConnection) {
billingClient.startConnection(new BillingClientStateListener() {
@Override
public void onBillingSetupFinished(int resultCode) {
isConnected = BillingClient.BillingResponse.OK == resultCode;
notifyConnectivityState();
if (isConnected) {
postConnection.run();
} else {
listener.onConnectedToBillingService(resultCode);
}
}
@Override
public void onBillingServiceDisconnected() {
isConnected = false;
listener.onDisconnectedBillingService();
}
});
}
public void release() {
this.billingClient.endConnection();
}
在低端设备上面临同样的问题。 – pratt
@pratt你有没有找到解决方案,我现在正面临这个问题,无法理解NPE来自 – spaceman
@spaceman,NPE来自谷歌计费库。为了解决这个问题,我简单地将billing-library项目作为模块添加到我自己的项目中,并编辑BillingClientImpl.java源文件。问题在于调用BillingManager.destroy()(通常在Activity.onDestroy()中)会调用BillingClientImpl.endConnection(),从而导致内部mContext引用无效。但是在某些情况下,您仍然可以在活动死亡后调用BillingServiceConnection.onServiceConnected(),并在内部使用已经为null的mContext。您可以选择不要使mContext无效或将其检查为空。 – pratt
