PayPal lures Android developers hunting for dollars

Online payment giant PayPal announces two developer tools that may soon get you using PayPal to purchase more goods on your Android phone.

For the next two days, Google geekdom will gather at the Google I/O developer conference in San Francisco, bringing with them an opportunity for publishers to spread their products' influence by getting developers on board--and maybe line their own corporate pockets in the process.

Take PayPal, for instance. At the conference opening on Wednesday, the online payment giant announced a developer tool for Android called the Mobile Payments Library, which allows application-authors to add PayPal-powered checkout to apps that sell goods or services, or collect donations.

The tool offers to track and secure customers' financial details, which could help keep smaller-fry developers from seeking other solutions for combating payment fraud online.

PayPal makes out in the deal, too. Developers will dish up 1.9 percent to 2.9 percent of the sale, plus 30 cents based on PayPal's tiered pricing structure for e-commerce, or a 5 percent plus 5 cents per each transaction fee for micropayments.

PayPal's Mobile Payments Library is already in effect for iPhone; here's more information on how it works.

Meanwhile, PayPal is also releasing a toolkit, called X Toolkit for Google App Engine (GAE), that will help developers using the GAE platform manage PayPal payments in their apps.
