Android uses adb pull or push to copy the mobile phone file to the computer, copy the mobile phone database to the computer, and copy the computer database to the mobile phone,
Let's talk about the adb command configuration first. If adb is not an internal or external command, it is not a runable program or batch file. Configure Environment Variables

MTK One-stop solution (Turn-key) mode before the mobile phone design and development process can be divided into the following 6 steps.The 1th step, design house from the chip manufacturers to get reference designs.Chip manufacturers according to their own market sector of the mobile phone market forecasts, determine the next few years what mobile phone needs, an
How many cores do you have on your phone? This is one of our most frequently asked questions when comparing the two phone differences. The number of CPU cores is indeed an important indicator of the performance of a mobile phone, but it is not the most accurate indicator.Take the most common Qualcomm Snapdragon in the

Yesterday, I saw an interview article in programmer. Meng Yan interviewed Chen Rong of the century of koteté on 3G mobile phone software. After reading this, I felt that Chen Rong had never done any mobile phone software. In fact, it doesn't matter if I don't know why. However, I am very disgusted with Chen Rong's pull of "Longhorn" and "metedata" and "the direction of software development is coming soon fr

The success is that the total memory and current available memory of the Android mobile phone are successfully read. This is just an example. You can expand it in the opposite way. Of course, we can also read "/proc/cupinfo" to obtain the
Android CPU Power consumption testWhen testing Android apps, don't just focus on the app's features, but the app's performance metrics, CPU, memory, traffic, power, and more. Briefly describe the CPU power consumption in the battery test.Factors that affect power consumption

If you forget your password, you can restart your phone by restoring the factory settings. The specific actions are as follows:
1. In the shutdown state, press the Power key to start the phone.
2. Quickly press and hold down the volume button until the exclamation point (!) interface appears on the screen. This interface prompts your phone to resume factory s
CPU clock speed, that is, the clock frequency (cpuClock speed ). In general, the CPU is as high as, And the is the "CPU clock speed ". Many people think that the CPU clock speed is its running speed. The clock speed of the CPU indicates the speed at which the digital pulse s
performance, data is merged and placed in a buffer before being sent to the next level. This increases the write latency, because after the first write to the buffer, wait for subsequent writes before sending.4. Concurrency and parallelismParallelism: the ability to load and start execution of multiple executable programs (for example, answering telephones and eating at the same time). To take advantage of multi-core processor systems, applications need to run on multiple CPUs at the same time,

Question 2: Why does the CPU display only 208 frequency?
The MTK6516 chip is composed of two chips, ARM9416MHz and ARM7208MHz. If you say dual-core, the true dual-core is absolutely tearful. What does MTK start from, the high integration reduces the production cost of mobile phones. MTK6516 is not a CPU, but a chipset.

And in order to ensure that its model has been a continuous gimmick can do marketing means, domestic mobile phone brand also played early 2K screen. Last year Meizu launched a high-profile launch
