php custom apk installation package example, phpapk installation package

The example in this article describes the method of customizing the php apk installation package and shares it with everyone for your reference. The specific implementation method is as follows:

As we all know, the apk format installation file is the installation file of the android smart system. Let's take a look at an example of using php to implement a customized apk installation package.

1. Demand:

It is necessary to carry out an activity of recommending friends to install the product, and each member downloads his own exclusive installation package (which records the relevant information of the member).

2. Ideas:

After understanding, I found that the apk installation package turned out to be just a vest of zip. You can use the ZipArchive class of php to operate the file.

3. Implementation code:

Copy code The code is as follows:

// Source file
$apk = "gb.apk";
// Generate temporary file
$file = tempnam("tmp", "zip");
// Copy file
if(false===file_put_contents($file, file_get_contents($apk))){
exit('copy failed!');
}
//Open temporary file
$zip = new ZipArchive();
$zip->open($file);
//Add file
// Since apk is limited to modifying files in this directory, otherwise an invalid apk package will be reported
$zip->addFromString('META-INF/extends.json', json_encode(array('author'=>'deeka')));
// Close zip
$zip->close();
// Download file
header("Content-Type: application/zip");
header("Content-Length: " . filesize($file));
header("Content-Disposition: attachment; filename=＼"{$apk}＼"");
// Output binary stream
readfile($file);
// Delete temporary files
unlink($file);

I hope this article will be helpful to everyone’s PHP programming design.

Can a php page send messages to an Android apk program that accesses it?

Your current approach is the only feasible approach. You can only refresh the APK regularly. Unless the APK and the server remain connected, the server's PHP is the service to find the APK, because your APK is not a server and cannot be executed in reverse.

If you want to reduce the pressure on the server, you must make your APK a server, listen on a network port, and allow other devices on the network to connect. However, this project will be very large, and the logic of APK and PHP will become very complicated, because PHP needs to find APK when needed. If the phone is turned off, it will have to delay the search again, and in order to wait for PHP to connect at any time, APK needs to use services. Work the way you want and be on call at any time.

What should I do if I download the mobile program and download the apk format into php?

The php file is a dynamic web page, and the downloaded php file records the address of the apk file. You can only click on it to open the web page and download it. When downloading in the future, right-click on the link and look at the properties. If the address bar ends with apk, you can use your method. If not, you need to click on the link and continue looking...
