Android 权限

系统6.0后需要动态获取权限

1. 判断系统版本 Build.VERSION.SDK_INT >= 23

2. 判断是否有对应的权限 int checkCallPhonePermission = ContextCompat.checkSelfPermission(WelcomeActivity.this, Manifest.permission.READ_PHONE_STATE); if (checkCallPhonePermission != PackageManager.PERMISSION_GRANTED)

3. 请求权限 requestPermissions(new String[]{Manifest.permission.READ_PHONE_STATE}, REQUEST_CODE_READ_PHONE_STATE);

4. onActivityResult中处理授权结果

部分机型不会弹出授权框(小米, 华为等)

这些机型一般是到了调用对应功能时, 才会调用授权, 所以需要先请求权限, 然后模拟调用对应功能, 最后再请求权限

小米手机授权BUG

小米部分手机ContextCompat.checkSelfPermission(WelcomeActivity.this, Manifest.permission.READ_PHONE_STATE) 不会返回正确的结果

需要使用下面判断

AppOpsManager appOpsManager = (AppOpsManager) getSystemService(Context.APP_OPS_SERVICE);
int checkOp = appOpsManager.checkOp(AppOpsManager.OPSTR_READ_PHONE_STATE, Process.myUid(), getPackageName());
if (checkOp != AppOpsManager.MODE_ALLOWED) {
    requestPermissions(new String[]{Manifest.permission.READ_PHONE_STATE}, REQUEST_CODE_READ_PHONE_STATE);
    return;
} else {
    //获取权限后的操作

}

if (Build.VERSION.SDK_INT >= 23) {
    int checkCallPhonePermission = ContextCompat.checkSelfPermission(WelcomeActivity.this, Manifest.permission.READ_PHONE_STATE);
                if (checkCallPhonePermission != PackageManager.PERMISSION_GRANTED) {
                    requestPermissions(new String[]{Manifest.permission.READ_PHONE_STATE}, REQUEST_CODE_READ_PHONE_STATE);
                    return;
                } else {
                    //适配小米机型
                    AppOpsManager appOpsManager = (AppOpsManager) getSystemService(Context.APP_OPS_SERVICE);
                    int checkOp = appOpsManager.checkOp(AppOpsManager.OPSTR_READ_PHONE_STATE, Process.myUid(), getPackageName());
                    if (checkOp != AppOpsManager.MODE_ALLOWED) {
                        requestPermissions(new String[]{Manifest.permission.READ_PHONE_STATE}, REQUEST_CODE_READ_PHONE_STATE);
                        return;
                    } else {
                    //获取权限后的操作

                    }
                }

            } else {
            //获取权限后的操作
            }
}

没有权限跳转到设置中的权限页面

class PermissionUtil {

    companion object {
        fun gotoPermission(context: Context) {
            val brand = Build.BRAND//手机厂商
            if (TextUtils.equals(
                    brand.toLowerCase(),
                    "redmi"
                ) || TextUtils.equals(brand.toLowerCase(), "xiaomi")
            ) {
                gotoMiuiPermission(
                    context
                )//小米
            } else if (TextUtils.equals(brand.toLowerCase(), "meizu")) {
                gotoMeizuPermission(
                    context
                )
            } else if (TextUtils.equals(

                ) || TextUtils.equals(brand.toLowerCase(), "honor")
            ) {
