Download Util File
Above i have provided the util links which will work for requests of any type of file.
- if you want to install packages or something else you have to mention permissions like this in your manifest file..
<uses-permission
android:name="android.permission.READ_EXTERNAL_STORAGE"
android:maxSdkVersion="32" />
<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE"
android:maxSdkVersion="29" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.POST_NOTIFICATIONS" />
<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
android:name="androidx.core.content.FileProvider"
android:authorities="com.prologic.invoice.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths" />
</provider>
- you will also need object file which is down below:-
import android.content.ActivityNotFoundException
import android.content.ClipData
import android.content.Context
import android.content.Intent
import android.net.Uri
import android.os.Build
import android.widget.Toast
import androidx.core.content.FileProvider
import com.prologic.invoice.BuildConfig
import java.io.File
object FileOpen {
fun shareFIle(context: Context, file: File) {
val shareIntent = Intent(Intent.ACTION_SEND)
shareIntent.type = "application/pdf"
val uri = FileProvider.getUriForFile(context, context.packageName + ".provider", file)
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
shareIntent.putExtra(Intent.EXTRA_STREAM, uri)
context.startActivity(Intent.createChooser(shareIntent, "Share Shop Certificate"))
}
fun openFile(context: Context, file: File) {
try {
val uri: Uri
val intent = Intent(Intent.ACTION_VIEW)
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY)
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
uri = FileProvider.getUriForFile(context, context.packageName + ".provider", file)
intent.clipData = ClipData.newRawUri("", uri)
} else {
uri = Uri.fromFile(file)
}
if (file.toString().contains(".doc") || file.toString().contains(".docx")) {
intent.setDataAndType(uri, "application/msword")
} else if (file.toString().contains(".pdf")) {
intent.setDataAndType(uri, "application/pdf")
} else if (file.toString().contains(".ppt") || file.toString().contains(".pptx")) {
intent.setDataAndType(uri, "application/vnd.ms-powerpoint")
} else if (file.toString().contains(".xls") || file.toString().contains(".xlsx")) {
intent.setDataAndType(uri, "application/vnd.ms-excel")
} else if (file.toString().contains(".zip")) {
intent.setDataAndType(uri, "application/zip")
} else if (file.toString().contains(".rar")) {
intent.setDataAndType(uri, "application/x-rar-compressed")
} else if (file.toString().contains(".rtf")) {
intent.setDataAndType(uri, "application/rtf")
} else if (file.toString().contains(".wav") || file.toString().contains(".mp3")) {
intent.setDataAndType(uri, "audio/x-wav")
} else if (file.toString().contains(".gif")) {
intent.setDataAndType(uri, "image/gif")
} else if (file.toString().contains(".jpg") || file.toString()
.contains(".jpeg") || file.toString().contains(".png")
) {
intent.setDataAndType(uri, "image/jpeg")
} else if (file.toString().contains(".txt")) {
intent.setDataAndType(uri, "text/plain")
} else if (file.toString().contains(".3gp") || file.toString()
.contains(".mpg") || file.toString().contains(".mpeg") || file.toString()
.contains(".mpe") || file.toString().contains(".mp4") || file.toString()
.contains(".avi")
) {
intent.setDataAndType(uri, "video/*")
} else if (file.toString().contains(".apk")) {
installApp(context, file)
return
} else {
intent.setDataAndType(uri, "*/*")
}
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
context.startActivity(intent)
} catch (e: ActivityNotFoundException) {
Toast.makeText(
context, "No application found which can open the file", Toast.LENGTH_SHORT
).show()
}
}
fun installApp(context: Context, file: File) {
val install = Intent(Intent.ACTION_VIEW)
install.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
install.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
val uri = FileProvider.getUriForFile(
context, BuildConfig.APPLICATION_ID + ".provider", file
)
install.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
install.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true)
install.data = uri
context.startActivity(install)
} else {
val appInstallPath = "application/vnd.android.package-archive"
install.setDataAndType(Uri.fromFile(file), appInstallPath)
context.startActivity(install)
}
}
} you will also need this function in your constant or common class
fun getDialog(context: Context, layoutId: Int): Dialog {
val dialog = Dialog(context)
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE)
dialog.window?.setBackgroundDrawableResource(R.color.trans)
val width = Utils.getScreenWidth(context)
dialog.setContentView(layoutId)
val layout = dialog.findViewById<ConstraintLayout>(R.id.main_layout)
val params = layout.layoutParams
params.width = width - (width * 13 / 100)
layout.layoutParams = params
return dialog
}fun isNetworkAvailable(context: Context): Boolean {
val manager = context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
val capabilities = manager.getNetworkCapabilities(manager.activeNetwork)
if (capabilities == null) return false
else if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR)) return true
else if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI)) return true
else if (capabilities.hasTransport(NetworkCapabilities.TRANSPORT_ETHERNET)) return true
} else {
val activeNetworkInfo = manager.activeNetworkInfo
if (activeNetworkInfo != null && activeNetworkInfo.isConnected) {
return true
}
}
return false
}you will need download layout also
