How to make money in the Android Market Part 1-paid app

With the successful transaction of the first paid app, I think it is necessary to write down how to authenticate, publish, and make money on the Android app, I also hope you can develop some free or paid Android software if you have the necessary conditions. There will be many opportunities for mobile development in the future.

We will not detail how to develop Android apps here.ArticleLarge.

Before publishing an app, you need a Google ID and register it as Android developer.
(Link: http://www.android.com/market ).
You can apply for the 25 USD payment. after application, you can also purchase a G1 development machine, but such a machine cannot be used to buy a paid app on the market. Because it has the root permission, some copyright restrictions can be easily cracked.

If you want to release paid software, you need to register Google Checkout. A credit card is enough.
If you do not have a legal tax return identity in the United States, the monthly income ceiling is $500. the excess part of the tax will be withheld first to prevent tax evasion. in addition, you need a bank account. Google must pass the authentication before you can make a payment for your account.

Currently, G1 in the United States can only view apps released to the U.S. market, and UK can only view UK, so you must have a G1 corresponding to your target region, so that you do not see your app at that time.

After completing the above steps, you can start to publish your app.

The release process is very simple. First, generate an APK file in eclipse for your app.

The specific method for passing jarsigner authentication is as follows:

To put it simply, you need to generate a keystore file, use this file to sign your app, and then upload it to market.
You also need to fill out some forms in the middle, such as some information about your app, category, price, and so on.
After the upload, the app will be published immediately. Google does not have any two certifications, so it is very fast.

My first paid app is shopfusion pro. this is a small software for discount websites to find the discount and promotion products you need. the server processes RSS data of different websites (PHP + MySQL ). then transmitted to the Android app in JSON format. this app has a free version (with ADS) named shopfusion. the predecessor of this software is dealsdroid. dealsdroid was created on a certain day in February. It only took one day in total. So far, there have been more than 3000 users. dealsdroid has no server side and all RSS processing is on the client side, so the speed is slow, especially under the GSM edge. if you are interested, you can try it later. You can see it only in US version G1. if you have extra rice, buy one ~~~ It's hard to write so many words ~~~
 
If you can earn more money, you just need to earn more. You can make your own money. As for how to spend it... view my desktop photos ~~~
