java - Java - app crash when using in app purchase

问题描述

So I have experienced some issue with in app purchase in my app.

I have started working on an old (8 months old) project I had earlier, but I am having some issue with app purchase. The app is already live on Play Store, so in app purchase is active.

In build.gradle (:app) I have changed from:

dependencies {
  implementation 'com.android.billingclient:billing:2.2.1'

to this:

dependencies {
  def billing_version = "3.0.0" // In App Purchase
      implementation "com.android.billingclient:billing:$billing_version"

This is the full code of my UpgradeActivity.java:

        return pref.getBoolean(constantName, false);

    }

    private void setBoolInPref(Context context,String prefName, String constantName, Boolean val) {
        SharedPreferences pref = context.getSharedPreferences(prefName, 0); // 0 - for private mode

        SharedPreferences.Editor editor = pref.edit();
        editor.putBoolean(constantName, val);
        //editor.commit();
        editor.apply();
        // Update 2015: Android recommends the use of apply() now over commit(),
        // because apply() operates on a background thread instead of storing the persistent data immediately,
        // and possible blocking the main thread.
    }
}

Basically what happens when pressing the upgradeButton is that the app crashes. I cannot figure out what I am doing wrong. I am using the correct SKU, and the app has been live on Play Store for over a year now.

This is the error log I get when pressing the upgradeButton:

I/zygote: Do partial code cache collection, code=124KB, data=72KB

Not sure what to look at here, but I can see that java.lang.IllegalArgumentException: SKU cannot be null., but sku has already been declared: private String sku = "com.pinloop.testproj.pro";. Any ideas?

您默认启用了升级按钮，并且在 upgradeAction 方法中没有空检查
您在 java 中通过 == 而不是 .equals 比较字符串
您正在设置升级 onclick 监听器 2 次
