HTC EVO 4G :: Will Formatting Sdcard Via Phone Solve Sdcard Mount Read Only Errors

Aug 16, 2010

I replaced my original sdcard with a sandisk 16gb card. Everything went well until I started getting these blasted read on errors. Earlymon suggested a fix from another board but I don't have a stand alone card reader so I couldn't do it that way.

I was wondering if I just backed up all my stuff from my sdcard to my iMac and then just reformatted my sdcard via the phone, would that solve my problems?

Android :: Why I Get Permission Alert?

Apr 7, 2010

I compiled my app in Eclipse and export it as signed application package, when I install it on my G1, I got "phone calls" and "storage" permission alert, "phone calls" permission said: "read phone state and identity", "storage" permission said :"modify/delete SD card contents". but in my AndroidManifest.xml file, I never define these two permission, and my application never need  the two permissions. Does anybody know why I get the permission alert? I use ADT 0.9.6. is that possible ADT compiler or signed tools inject the two permission into my app?

Android :: Testing Uses Permission

Jun 24, 2009

I'm prepping my first app for publishing and am a bit confused about how to properly test my <uses-permission> tags.. if i don't specify any permissions my app runs with no complaints on my G1. I tried installing it via "adb install" as well as with the eoeAppInstaller (as somebody had recommended). Also, the app is signed with my own certificate (not the debug cert). given that it works fine with no permissions (btw, it accesses camera and sd card), how will I know if I've set all of the proper <uses- permission> tags?

Android :: How Could An App Get System Permission?

Aug 5, 2010

I wrote a test to check what kind of permissions are allowed to an application.  A test run in the emulator shows the following error: However, a search of SDK doc revealed that only the following permissions are reversed to the system: Code...
This brings up 2 questions: (1) Why did the emulator deny other permissions in addition to those 4 system ones? (2) How could an app get the system permission?  If this can only be done by building a custom Android like an OEM build, where in the Android platform does it check for system-level permission?

Android :: Using Permission That Doesn't Exist

Feb 10, 2010

I saw on that my app can declare a permission:


However, what if is not yet installed on the device?

[a] I tested with "adb install", and Foo was installed on the device without incident. The only thing I see is "W/PackageManager(   62): Unknown permission in package"

[b] if I upload Foo into Android Market, but the user has not yet installed "myapp", will he be able to see Foo in market?

[c] if the answer to [b] is yes (I really hope so, or else it will be a major bummer ...) what message will the user see regarding Since the description of this permission is declared only in "myapp", without "myapp" installed, will the user just see the name of the permission, which probably doesn't mean much?

If [c] is true, would this be a weakness to the Android permission system/Android Market? As long as I can fool the user to install my app first, I would be able to gain permissions that the user would not have otherwise granted me (had he known the true nature of such permissions).

Android :: Cannot Install App If Permission Is Granted

May 8, 2009

I am sure that the permission is granted as I declare this in my manifest. Hence the app wouldn't be installed if the user didn't grant the permission.

(a) My guess is that it's a rooted phone where the app is started from an SD card (or similar) whereby the original user id has changed after the install. (b) This could be a Cupcake "feature". Acquiring wake locks has gone down a similar path as turning GPS on?

I am trying to track down (a) with my users, but this takes some time. I meanwhile now that at least one user uses a JF image. Anybody else has experience with that issue? if (b) might be valid? The app works on my 1.5 emulator and on > 400 phones with Cupcake, at least it is installed on them and users don't submit bug reports. So I guess (b) is not the case, but who knows?

Android :: Upgrade With SD Card Write Permission

Oct 23, 2009

If you have an app that targets 1.6 ( using targetSdkVersion=4 ) and that is still backward compatible with 1.5 (using minSdkVersion=3) , and it has the new WRITE_EXTERNAL_STORAGE permission because it writes to the SD card, there is a problem when the OS is upgraded to 1.6. If a user has Android 1.5 with the app installed, and then gets Android 1.6, the permission is not granted and writing fails. The issue can be solved if the user re-installs the app. I have not experienced the issue myself, but a few users have reported it. Can anybody else confirm this. There is not much that can be done about it, but it would need to be adressed if there is another OS upgrade.
