By default, if the free storage space on device is less than 10%, Android displays a "Low storage space" warning and doesn't allow installing any app even if the free space is 100 MB and the app size is only 5 MB. This could be annoying.

There is a tip to reduce the threshold as follows but it doesn't work on CM 10.1:

To reduce from 10% to 5% warning from your “adb shell”:

Code: Select all

# sqlite3 /data/data/com.android.providers.settings/databases/settings.db
sqlite> insert into secure (name, value) VALUES('sys_storage_threshold_percentage','5');
sqlite> insert into gservices (name, value) VALUES('sys_storage_threshold_percentage','5');
sqlite> .quit
# reboot


*** don't include the # or sqlite>, those are the console prompts... ***

I did a search but only found the above tip. So I decided to look at the CM 10.1 source code and found that it uses the global table.

Code: Select all

private long getMemThreshold() {
        long value = Settings.Global.getInt(
                              mContentResolver,
                              Settings.Global.SYS_STORAGE_THRESHOLD_PERCENTAGE,
                              DEFAULT_THRESHOLD_PERCENTAGE);


CM 10.1 DeviceStorageMonitorService

Code: Select all

public static final class Global extends NameValueTable {
   ...
   public static final String
                SYS_STORAGE_THRESHOLD_PERCENTAGE = "sys_storage_threshold_percentage";

CM 10.1 Settings

Therefore, in order to reduce the threshold in CM 10.1, the following code must be used instead:

Code: Select all

# sqlite3 /data/data/com.android.providers.settings/databases/settings.db
sqlite> insert into global (name, value) VALUES('sys_storage_threshold_percentage','5');
sqlite> .quit
# reboot

I've tested it and it worked.

Update: This should work on CM 10.2 and CM 11 as well. I looked at CM 10.2 and CM 11 source code. It also uses the global table.

Code: Select all

final StorageManager sm = StorageManager.from(context);
        mMemLowThreshold = sm.getStorageLowBytes(DATA_PATH);

CM 10.2 DeviceStorageMonitorService
CM 11 DeviceStorageMonitorService

Code: Select all

public long getStorageLowBytes(File path) {
        final long lowPercent = Settings.Global.getInt(mResolver,
                Settings.Global.SYS_STORAGE_THRESHOLD_PERCENTAGE, DEFAULT_THRESHOLD_PERCENTAGE);

CM 10.2 StorageManager
CM 11 StorageManager

You the man bro, I was looking for this exactly. I have a 4GB ext4 partition on the SD card and even though I have 400 MB of storage space, it doesn't let me update apps.

Thanks, this suggestion helped.

EDIT: Thanks, you tip worked.
