I would like to publish my app on the Android store but I can not get my app to work in the emulator. I cannot figure out why I cannot run my app when so many have published with the same tools as me in the past.

I have downloaded the lastest Android SDK and installed all the API's. There are alot of 2.3.3 devices and my app supposedly supports as far back and API level 3 so I am assuming my app should be working on API level 10. However my app complains that it has been built for ARM5TE and that the device supports ARM5T.

I cannot figure out what this implies and I am able to build with ARM5T but have no idea if that would then mean my app would not work on ARM5TE. I know that most devices are ARM based but I have no idea how many are ARM5TE and ARM5T. I wanted to support the 90% of devices that use the app store that support open GL 2.0.

  • ARM5TE is the minimum arm processor android supports. Configure your emulator so it acts like an ARM5TE. – auselen Mar 26 '13 at 12:06
  • Oh wow thanks for the info, wow wonder why the Android emulator would default to ARM5T. – user2210905 Mar 26 '13 at 12:33
  • I cannot find any documentation on how to configure my 2.3.3 AVD to use ARM5TE instead of ARM5T, would anyone mind posting a link? – user2210905 Mar 26 '13 at 13:30
  • You can use the `ARM5TE` or even better. The `ARM5TE` was state of the art in ~2000-2004. Today, it is a rather old CPU. I use it, but not for Android. It is unlikely anyone would make an Android device with an `ARM5TE`, yet alone an `ARM5` only. The ARM has confusing numbering. An ARM926 is an ARM5TE. The *926* is a particular implementation. For ARM concept wise, a [Pentium 4](http://en.wikipedia.org/wiki/Pentium_4) is like an ARM5TE . Whereas a *Willamette*, *Northwood*, etc is like an *ARM926*. – artless noise Mar 26 '13 at 17:48
  • so why are my AVD's emulating ARM5T with no way to change it – user2210905 Mar 27 '13 at 12:02
  • Just as a relief to you. All of my released game, which are made in marmalade, never worked in Android emulator. I had the devices, so I never worried about emulator. – 0xC0DED00D Mar 27 '13 at 12:55

To improve the ARM architecture for digital signal processing and multimedia applications, DSP instructions were added to the set.[30] These are signified by an "E" in the name of the ARMv5TE and ARMv5TEJ architectures. E-variants also imply T,D,M and I.

The new instructions are common in digital signal processor architectures. They include variations on signed multiply–accumulate, saturated add and subtract, and count leading zeros.

Most Android phones released in the last couple of years are based on ARMv7-A, which also supports these DSP instructions.

  • Great answer, thank you. I am assuming then that I can safely release a ARM5T version or if possible find a way to enable ARM5TE in the emulator and release an ARM5TE version. – user2210905 Mar 26 '13 at 12:11
