Writing to file on android: Null Function Pointer

[Michelle Brodeur]

Ok, read a lot of post, seem sto be written correctly.

Here is the code:

in the application.xml we have

<!— Android Permisions —>

<android permission=“android.permission.WRITEEXTERNALSTORAGE” />

In our test function we have:

public static function testWrite( ):Bool

{

// Attempting to open/create the file:

var lfileOut:Dynamic = null;

trace(“write path and file: ” + SystemPath.applicationStorageDirectory + “test.dat” );

try {

lfileOut = File.write( SystemPath.applicationStorageDirectory + “test.dat”, true );

} catch ( perror:Error ) { return false; }

trace(“fileout ” + lfileOut + “.”);

if ( lfileOut != null )

{

trace( “Trying to get the uuid.”);

var ldeviceUID:String = Device.getUuid();

trace(“the uuid is: ” + ldeviceUID + “.” );

var ldeviceUIDLength:Dynamic = ldeviceUID.length;

trace(“The length of the UID is ” + ldeviceUIDLength + “.”);

lfileOut.writeString( ldeviceUIDLength );

trace(“The length of the UID is written.” );

lfileOut.writeString( ldeviceUID );

trace(“file was written.”);

lfileOut.close();

trace(“File was closed.”);

return true;

}

// If somthing went wrong we return false:

return false;

}

When we run it on the android we get this:

I/trace (23094): TestIO.hx:49: write path and file: openfl.utils.Sys

temPathtest.dat

I/trace (23094): Lib.hx:300: [fileopen,openfl.utils.SystemPathtest.dat]

I/trace (24692): TestIO.hx:49: write path and file: openfl.utils.Sys

temPathiaptoken.dat

I/trace (24692): Lib.hx:300: [fileopen,openfl.utils.SystemPathtest.dat]

I/trace (25827): IAPUnlockHelpers.hx:49: write path and file: /data/data/com.A

byss.test/filestest.dat

I/trace (25827): IAPUnlockHelpers.hx:54: fileout FileOutput.

I/trace (25827): IAPUnlockHelpers.hx:57: Trying to get the uuid.

I/trace (25827): IAPUnlockHelpers.hx:59: the uuid is: ************

I/trace (25827): IAPUnlockHelpers.hx:61: The length of the UID is 36.

I/trace (25827): Lib.hx:300: Null Function Pointer

Any ideas?

var ldeviceUIDLength:Dynamic = ldeviceUID.length;

the problem is with using Dynamic. writeString() expects a string to be passed, you are however passing an Int as a Dynamic. You should convert the length into a string by either using Std.string() or var len = ldeviceUID.length + "";

Sorry No Joy

This did not work.

Big problem is why does the Try Catch not catch it for not making the file.

It comes back as a Type of “FileOutput” and so it passes a Null check.

We have tried byte, int, string

with lime clean application android

lime build application android

lime test application android

everything is the latest version with update and upgrade.

Ok any one reading this post, this was the prblem.
var fileOut:Dynamic = null;

should be

var fileOut = null;

Who knew.....

thanks all
