If a device has an SD card, you use: Environment.getExternalStorageState() If you don’t have an SD card, you use: Environment.getDataDirectory() If there is no SD card, you can create your own directory on the device locally. //if there is no SD card, create new directory objects to make directory on device if (Environment.getExternalStorageState() == null) … Read more
The default storage duration is static, but default linkage is external. You’re not the only one to find it a bit confusing. The C Book (always a good reference) says: “You’ll probably find the interactions between these various elements to be both complex and confusing: that’s because they are!” The section with that quote, Declarations, … Read more
From S. Prakash, found at the MySQL forum: SELECT table_schema “database name”, sum( data_length + index_length ) / 1024 / 1024 “database size in MB”, sum( data_free )/ 1024 / 1024 “free space in MB” FROM information_schema.TABLES GROUP BY table_schema; Or in a single line for easier copy-pasting: SELECT table_schema “database name”, sum( data_length + … Read more
I’ve been searching for a solution. I resolve this issue as follows. After platform.ready() function I created a directory as follows. this.file.createDir(this.file.externalDataDirectory , ‘Videos’, false).then(() => { // console.log(‘Directory created successfully’); }).catch(() => { // console.log(‘Failed to create directory’); }); To download videos inside the created directory import { FileTransfer, FileTransferObject } from ‘@ionic-native/file-transfer’; import … Read more
You can use the Web Storage API (Window.localStorage or Window.sessionStorage). Check out this article on html5doctor for a more in-depth explanation. The Web Storage API is supported by all modern browsers at this point. The read-only localStorage property allows you to access a Storage object for the Document’s origin; the stored data is saved across … Read more
Example: Getting human readable size like 1 Gb String memory = bytesToHuman(totalMemory()) /************************************************************************************************* Returns size in bytes. If you need calculate external memory, change this: StatFs statFs = new StatFs(Environment.getRootDirectory().getAbsolutePath()); to this: StatFs statFs = new StatFs(Environment.getExternalStorageDirectory().getAbsolutePath()); **************************************************************************************************/ public long totalMemory() { StatFs statFs = new StatFs(Environment.getRootDirectory().getAbsolutePath()); long total = (statFs.getBlockCount() * statFs.getBlockSize()); return total; … Read more
If you use Environment.getExternalStorageDirectory() (or Context.getExternalFilesDir() for API level 8 and up) as the place for your json file, then I believe the size will be limited by the available space in the external storage (usually an SD card). For most devices, I believe there are no fixed limits built into Android for external file … Read more
You shouldn’t do that, you shouldn’t force the users to keep data on their phones without their consent. Anyway, application data directory will be deleted after uninstall, but NOT after an update The only way to have persistent data is to use the SD card, but again, users won’t like to have the data on … Read more
When I use /storage/sdcard0/ on them the code runs successfully but when I use Galaxy Nexus 3 the code fails. /storage/sdcard0/ is not internal storage. It is external storage. (BTW, since there is no device named “Galaxy Nexus 3”, I am assuming that you simply meant “Galaxy Nexus”) To find locations on internal storage for … Read more
it is packaged with your binary — by packaged I mean hard-wired, so yes you can return it and use it elsewhere — you won’t be able to alter it though, and I strongly suggest you declare it as: const char * x = “hello world”;
