Hi All!
I read this thread, and some advanced concepts are being discussed here I
see!
(Sorry for being a lay man developer, please go easy on me)
I am using this implementation, and I can download up to ~30 MB of data on
my A53 Samsung Android device with it:
```
// File download
function downloadResult(taskId) {
cordova.plugin.http.sendRequest(
`http://192.168.2.18:3007/poc4/download/${taskId}`,
// `https://aiffamp3.com/poc4/download/${taskId}`, // Production URL
{
method: 'get',
responseType: 'arraybuffer',
headers: { 'Accept': 'audio/mpeg' }
},
function (response) {
console.log('Download successful, saving file');
const blob = new Blob([response.data], { type: 'audio/mpeg' });
saveMP3(
blob,
function (savedPath) {
statusDiv.innerHTML = `Download complete! File saved
to:<br>${savedPath}`;
convertBtn.disabled = false;
},
function (error) {
console.error('Save file failed:', error);
statusDiv.textContent = `Failed to save file: ${error.message ||
'Unknown error'}`;
convertBtn.disabled = false;
}
);
},
function (error) {
console.error('Download failed:', error);
statusDiv.textContent = `Download failed: ${error.error ||
error.message || 'Unknown error'}`;
convertBtn.disabled = false;
}
);
}
// Save MP3 file to device
function saveMP3(blob, successCallback, errorCallback) {
window.resolveLocalFileSystemURL(cordova.file.externalRootDirectory,
function (rootDir) {
rootDir.getDirectory('Download', { create: true }, function
(downloadDir) {
const fileName = `converted_${Date.now()}.mp3`;
downloadDir.getFile(fileName, { create: true }, function (fileEntry)
{
fileEntry.createWriter(function (writer) {
writer.onwriteend = function () {
successCallback(fileEntry.toURL());
};
writer.onerror = function (error) {
errorCallback(new Error('Failed to write file'));
};
writer.write(blob);
}, function (error) {
errorCallback(new Error('Failed to create file writer'));
});
}, function (error) {
errorCallback(new Error('Failed to create file'));
});
}, function (error) {
errorCallback(new Error('Failed to access Download directory'));
});
}, function (error) {
errorCallback(new Error('Failed to access external storage'));
});
}
}
```
The app crashes when trying to download ~60 MB of data.
I was looking for a bullet proof solution capable to download files .mp3 up
to ~ +300 MB.
I'm using this for the request: cordova-plugin-advanced-http
I'm using this for the download: cordova-plugin-file (uses cordova.file).
All help or recommendations would be appreciated.
