Android API compatibility on different versions of the system

As the Android version continues to update, the new API is constantly gushing, and sometimes the high-version API is crash in the lower version.

If the minsdkversion setting is too low, the error will be in the build (call requires API level 9);

In order to compile can pass, can add @SuppressLint("NewApi") or@TargeApi(9)注解。

This is only compiled through, the runtime will still be crash.

The right approach

In order to run without error, you need:

1. Determine the runtime version, this method is not called in the low-version system

2. In order to ensure the integrity of the function, we need to provide the low-version function

Summary: Using a method higher than minSdkVersion the API level requires:

1. If @TargeApi($API_LEVEL) the use can be compiled through, then do not use @SuppressLint("NewApi") ;
2. Run-time judgment API level; This method is only called in an API level system that is high enough to have this method;
3. Ensure functional integrity and ensure that low API versions provide functionality through other methods.

Easy to ignore the API small details, fortunately, IDE development tools, will automatically remind you of.
