Recently I learned IDA dynamic debugging so files. During the process, you must ensure that the android_server and IDA versions and the number of bits are the same. It also involves the number of bits of the mobile phone running cpu, that is, 32-bit or 64-bit. Therefore, it involves the cpu architecture of the mobile phone. to sum up.
View mobile phone cpu architecture commands:
adb shell
su
//查看cpu信息
cat /proc/cpuinfo| Serial number | cpu architecture | Description |
| 1 | AArch64 | ARM64 architecture |
1. armeabi-v7a: ARM processors of the seventh generation and above are used by most Android devices produced after 2011.
2. arm64-v8a: 8th generation, 64-bit ARM processor, few devices, Samsung GalaxyS6 is one of them.
3. Armeabi: The 5th and 6th generations of ARM processors are used more in early mobile phones.
4. X86: Tablets and emulators are used more.
5. X86_64: 64-bit tablet.
