Question

我正在使用applyBatch方法为其插入Android应用程序，我的内容解析器显示空指针异常。

public void import_contacts(File paramFile, int paramInt)
            throws IOException {
        String[] arrayOfString;
        i1 = 0;
        try {
            FileInputStream localFileInputStream = new FileInputStream(
                    paramFile);
            BufferedReader localBufferedReader = new BufferedReader(
                    new InputStreamReader(localFileInputStream));
            for (;;) {
                String str = localBufferedReader.readLine();
                if (str == null) {
                    localBufferedReader.close();
                    mProgress.setProgress(100);
                    mHandler.post(new Runnable() {
                        public void run() {
                            alertdialog_Contact(totalRecToImport
                                    + " Contacts were imported Successfully");
                        }
                    });
                    return;
                }
                i1++;
                float f = i1;
                mProgressStatus = ((int) (f / (paramInt / 100)));
                mHandler.post(new Runnable() {
                    public void run() {
                        mProgress.setProgress(mProgressStatus);
                    }
                });
                Log.d("TAG", str);
                arrayOfString = str.split(";");
                if (arrayOfString.length >= 4) {
                    // if (arrayOfString.length != 4) {
                    // break;
                    // }
//                  insertLine(arrayOfString[0], "", arrayOfString[3], "", "",

                    op_list = new ArrayList<ContentProviderOperation>();

我正在尝试插入10000个联系人，请告诉我必须遵循哪种方法？

Answer 1

您无法插入具有空帐户名和帐户类型的联系人。同时保持批量大小最多为50.帐户名称和类型应为可写帐户，或者您应在设备中创建自己的帐户。

如何提高联系人插入性能？
