获取版本号
/**
* 获取Android发布的版本
*/
public static String getVersion() {
return android.os.Build.VERSION.RELEASE;
}
/**
* 获取SDK的API Level
* @return
*/
public static int getSDK() {
return android.os.Build.VERSION.SDK_INT;
}
版本号适配
6.0的权限
protected boolean hasPermission(String permission) {
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP_MR1)
return (checkSelfPermission(permission) == PackageManager.PERMISSION_GRANTED);
return true;
}
通知的副标题 API LEVEL16才能使用
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
builder.setSubText("it is really basic");
}
API Level建议写成版本名VERSION_CODES, 少用数字
