As we all know, most of the information on Android phones can be obtained through code. For example, iQiyi's offline storage function has a maximum storage size/remaining storage size function.
Get the stored information on the SD card:
/**
* Total SD card size obtained
*
* @return
*/
private String getSDTotalSize() {
File path = ();
StatFs stat = new StatFs(());
long blockSize = ();
long totalBlocks = ();
return (this, blockSize * totalBlocks);
}
/**
* Get the remaining capacity of the SD card, and you can use the size
*
* @return
*/
private String getSDAvailableSize() {
File path = ();
StatFs stat = new StatFs(());
long blockSize = ();
long availableBlocks = ();
return (this, blockSize * availableBlocks);
}
The memory of the mobile phone system can also be obtained through the () method: as follows:
Get the system's memory size and available memory size:
/**
* Get the system memory size
* @return
*/
private String getSysteTotalMemorySize(){
//object to obtain the ActivityManager service ActivityManager mActivityManager = (ActivityManager)getSystemService(Context.ACTIVITY_SERVICE);
//Get MemoryInfo object memoryInfo = new () ;
//Get available memory in the system and save it on the MemoryInfo object (memoryInfo) ;
long memSize = ;
//Character type conversion String availMemStr = formateFileSize(memSize);
return availMemStr ;
}
/**
* Get the available memory size of the system
* @return
*/
private String getSystemAvaialbeMemorySize(){
//object to obtain the ActivityManager service ActivityManager mActivityManager = (ActivityManager)getSystemService(Context.ACTIVITY_SERVICE);
//Get MemoryInfo object memoryInfo = new () ;
//Get available memory in the system and save it on the MemoryInfo object (memoryInfo) ;
long memSize = ;
//Character type conversion String availMemStr = formateFileSize(memSize);
return availMemStr ;
}
