java - 如何以编程方式在android Q中获取IMSI？

Question

TelephonyManager getSubscriberId() 和 getSimSerialNumber() 在 android Q 中返回 null!

我正在使用 android studio IDE 进行 Java 编码!

TelephonyManager telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
telephonyManager.getSimSerialNumber(); //it is null

如果您的apk的targetsdk <30，即使在android 11中，您也可以通过以下方法获取ICCID，无需任何权限。

    Uri uri = Uri.parse("content://telephony/siminfo");
Cursor cursor = null;
ContentResolver contentResolver = getApplicationContext().getContentResolver();
cursor = contentResolver.query(uri,
        new String[]{"_id", "sim_id", "imsi","icc_id","number","display_name"}, "0=0",
        new String[]{}, null);
if (null != cursor) {
    while (cursor.moveToNext()) {
        String icc_id = cursor.getString(cursor.getColumnIndex("icc_id"));
        String imsi_id = cursor.getString(cursor.getColumnIndex("imsi"));
        String phone_num = cursor.getString(cursor.getColumnIndex("number"));
        String display_name = cursor.getString(cursor.getColumnIndex("display_name"));
        int sim_id = cursor.getInt(cursor.getColumnIndex("sim_id"));
        int _id = cursor.getInt(cursor.getColumnIndex("_id"));
        Log.d("Q_M", "icc_id-->" + icc_id);
        Log.d("Q_M", "imsi_id-->" + imsi_id);
        Log.d("Q_M", "phone_num-->" + phone_num);
        Log.d("Q_M", "sim_id-->" + sim_id);
        Log.d("Q_M", "display_name-->" + display_name);
    }
}
