How to expand SD-Card size

[geor...@googlemail.com]

Hello,

i have a 32GB sd-card. I installed the newest image of android 7.
After this the size of sd-card increase to 8GB (image size).

How i can expand the size to the real size?

Thx

Georg.

Could you please be more specific? Which Android distribution did you use? How did you install? Are you talking about the "userdata" partition in Android or the physical size of your card?

[Mario Holzinger]

for example you can use fdisk in linux to resize the data partition

simply follow https://minibianpi.wordpress.com/how-to/resize-sd/

but adapt the instruction to fit partition 4 (data partition) and the device name you are seeing in your linux distribution (sdxpx, mmcblkxpx, ...)

or use a Gparted Linux live image to boot from

or on windows search for a tool that can handle EXT4 partitions to resize them.

regards

Mario

Hi,

i will resize the physical size of my sd-card.
In the past i had a boot-cd with linux and a tool to resize.
But i cant find it anymore.

I anybody have a link to a image please tell me.

The install script for RTAndroid 7.0 will automatically repartition the sdcard and use its maximum size, if the "-p" flag is used.

Hi,

but i only flash a fixed image file to my sd-card.
Maybe android resize it by first start???

I don't tested becaus my rasberry pi 3 is ordered but not reached me now.
